    China's Experimental Advanced Superconducting Tokamak (EAST) fusion reactor


    The Experimental Advanced Superconducting Tokamak (EAST) fusion reactor, which replicates the energy generating process of the sun, was tested at the Institute of Plasma Physics under the Chinese Academy of Sciences (CAS) in Hefei, capital of east China's Anhui Province in February 2006.

    Fusion diagnostic developed at PPPL sheds light on plasma behavior at EAST

    "Fusion diagnostic developed at PPPL sheds light on plasma behavior at EAST
    by Staff Writers
    Princeton NJ (SPX) Aug 08, 2011

    An instrument developed by researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has enabled a research team at a fusion energy experiment in China to observe--in startling detail--how a particular type of electromagnetic wave known as a radiofrequency (RF) wave affects the behavior of hot ionized gas.

    In the experiment at EAST (the Experimental Advanced Superconducting Tokamak located at the Institute of Plasma Physics in Hefei, China), scientists employed a high-resolution, X-ray imaging crystal spectrometer (XICS) to observe how an RF wave changed the way a hot ionized gas known as a plasma moved in a vacuum vessel. Radiofrequency waves are similar to microwaves and are used to heat and drive current in plasma.

    The experimenters already knew that the RF wave, also called a lower-hybrid wave, drives current in the plasma. What they found was that the lower-hybrid wave also caused the plasma to flow as a whole and at high velocities through the vacuum vessel, a property they refer to as toroidal rotation. The spectrometer provided a two-dimensional look at the plasma, recording data at a rate of about 50 frames a second.

    That's important because not all parts of the plasma move uniformly. For example, if the inner part of the plasma near the vessel's core is moving at a different rate - or even in a different direction - than the rest of the gas, researchers want to know those details. Understanding the plasma flows is vital because it could lead to better approaches to confinement.

    The results were published in the June 6 edition of Physical Review Letters by researchers from the EAST team and PPPL's Manfred Bitter and Kenneth Hill. Bitter and Hill are experimentalists who have collaborated for more than 35 years.

    "With plasmas, you are dealing with very high temperatures and flow velocities," Bitter said. "Those must be determined from the radiation emitted by the plasma." The spectrometer designed by Bitter and Hill measures both the plasma temperatures and flow velocities, and it appears to offer a window onto the world of fusion plasmas.

    The observed plasma flow could be beneficial to progress in fusion research, according to the PPPL scientists. "ITER and future reactors cannot rely on the injection of neutral beams to impart momentum to the plasma and control the toroidal flow," Bitter said, noting that this is due to the scale of the experimental reactor presently under construction in France. ITER must rely on self-generated or RF-driven flow, meaning that this research is highly relevant to those projects.

    The new spectrometer allows researchers to study self-generated and RF-driven flow with the goal to control it in future reactors so that plasmas can be more carefully contained.

    The DOE Office of Science supports the spectrometer collaboration between the U.S. and the People's Republic of China (PRC) through the U.S.-PRC Fusion Cooperation Program.

    The spectrometer project includes researchers from EAST, PPPL, and the National Fusion Research Institute (NFRI) in Korea. Bitter and Hill helped design the instrument, which was installed on EAST.

    X-ray crystal spectrometers measure the frequencies and intensities of X-rays emitted by plasma impurities. Researchers can identify the impurity by the pattern of frequencies, or spectrum, of the X-ray light emitted to help them determine the plasma ion temperature, as well as the rotational velocity of the bulk plasma, from the Doppler broadening and Doppler shift of an X-ray peak.

    "This Doppler shift or change in frequency is exactly the same phenomenon as the change in the pitch of a train horn as the train passes by an observer," Hill said.

    The spectrometer designed by Bitter and Hill is made up of several components. It includes a "spherically bent crystal," a tiny piece of quartz that has been molded into a sphere. It also contains a two-dimensionally imaging X-ray detector and a beryllium window.

    EAST scientists have installed a second spectrometer on the tokamak based on the first spectrometer's design. Similar spectrometers designed by Bitter and Hill have been installed on experimental fusion machines in Korea and Japan, and at the Plasma and Fusion Science Center at the Massachusetts Institute of Technology, as well.

    Researchers at PPPL, managed by Princeton University and funded by the DOE's Office of Science, collaborate with scientists around the world to develop fusion as an energy source for the world. Fusion is the process that powers the Sun and other stars. In the interior of stars, matter is converted into energy by the fusion, or joining, of the nuclei of light atoms to form heavier elements."

    China and the rise of the driverless car

    "China and the rise of the driverless car
    Written by Harry Fairhead
    Thursday, 11 August 2011 13:52

    While Google makes headlines with its driverless car and even manages to lobby Nevada to legalize driverless cars on the public road - China quietly pushes ahead on its own.

    China Daily reports that on the 14th of July a Hongqui HQ3 travelled 286km in three hours 20 minutes without a driver at the wheel on an expressway linking Changsha and Wuhan, the capitals of Hunan and Hubei provinces.


    A Hongqui HQ3 of the type used in the project

    The project is being developed by the National University of Defense Technology.

    One of the research team is reported as saying:

    "We only set a maximum speed and then left everything to the car itself. It knew the speed limits, traffic patterns, lane changes and roads using video cameras and radar sensors to detect other cars. It was all controlled by a command center in the trunk."

    Technical details are limited but it is claimed that GPS wasn't used to navigate the car and it relied on its sensors not only to stay on the road but to work out which road to stay on. Unlike Google's the Chinese driverless car uses computer vision to navigate aided by laser range finders. As a result it cannot drive and night and so the entire journey had to be completed during daylight. It also encountered some problems with fog and indistinct road markings. It could be argued that relying on computer vision is a more sophisticated approach than using GPS and laser range finders but without more information it is difficult to be sure. As well as just driving in a single lane the car overtook other cars a reported 67 times at an average of 87km/h.


    Although no reason for building the driverless car has been given the statistics stress that "its" reaction times are around 40ms compared to 500ms for a human and so safety seems to be a concern. However Google's car has logged 140,000 miles with only two minor accidents to its name and one of those was caused by a human driver. It will take some effort to match this performance.

    China is late into the driverless car race and members of the team are aware of the doubt that surrounds the project because of the speed that they have been able to ... well.. it has to be said.. get up to speed.

    "Some foreign experts asked me directly whether the artificial intelligence system was really developed with our own proprietary technologies, while some humorously asked where the three tiny robots in charge of the accelerator, brakes and direction hid in the car!"

    The project isn't over and now they are co-operating with China's First Auto Works to produce an even better and perhaps commercial version."

    China cracks Europe's light rail market.

    China to export first light rail train to Europe - People's Daily Online

    China to export first light rail train to Europe
    By Liang Zhanye (People's Daily Online)
    14:45, August 11, 2011

    On Aug.10, the first high-tech light rail train produced for export to Europe came off the line, marking a significant achievement for CSR Zhuzhou Electric Locomotive Co., Ltd.

    Cracking the European market, which has the world's highest standards for rail transit, is extremely difficult, said Xu Zongxiang, the general manager of CSR Zhuzhou Electric Locomotive Co., Ltd.

    "[It] signifies that our innovation capability of equipment and technology in rail transit has been approved by the world class market," Xu said.

    The train is destined for Izmir, the third largest city in Turkey, which has light rail that goes through crowded areas with many sharp curves. The pathways are only 30 meters in radius and have abrupt slopes, so the safety and comfort of the train are a major concern.

    "Its rail transit market has been monopolized by international enterprises from Europe, the United States, Japan and Korea for a long time."

    The breakthroughs made by CSR Zhuzhou Electric Locomotive Co., Ltd. benefited from the individualized system design and the mature solutions approved by IRIS of the International Union of Railways.

    It has been said that the train’s maximum velocity is 80 kilometers per hour, and every single train has its individual operation mobility so that they can be organized into different groups on the basis of the number of passengers in the morning and evening.

    The articulated bogie can help the train freely swing and smoothly turn. When running down steep hills, the attraction between the track and the magnet assembly near the wheels can make an immediately brake. Designs like these greatly increase the comfort and safety. According to the professional test, indexes, including derailment coefficients, are two levels higher than other trains of a similar type.

    In regard to quality, there are more than 10,000 parts approved by European standards along with the materials complying with the world’s highest BS6853 environmental protection standard. Before the train left the factory, its durability and doors were tested 5,000 times and 1,000 times, respectively, as well as 12,400 cables that were examined one by one. Nuoka, the supervision engineer dispatched from Turkey, is satisfied with the whole quality and every single link in the production chain as a witness of the whole production process.

    It is said that 30 trains of this type will come into service in Izmir, the third largest city in Turkey, successively over the next two years. Fu Jianguo, the vice president of CSR Zhuzhou Electric Locomotive Cp., Ltd. announced that the company should regard the light rail project in Turkey as a stepping-stone to success and strive to create an internationalized CSR Zhuzhou Electric Locomotive Co., Ltd.

    Re: News on China's scientific and technological development.

    I just glance through the last few posts, and suddenly have a feeling:

    This (the thread) should be the treasure cave for any China-basher! - You guys just nailed almost every piece of news a basher would prey for, and an "usual audiance" in half world away would usually scary for, while they would not give any of your guys any credits.

    Also, I would tell any friend from Propaganda Department I know (if any), to stick to this thread. A hell lot easier to write a Baguwen report, if citing from here, while do not give any of your guys any credits.

    Sigh... see how "credit-less" you guys are doing? (At least you guys made effort to "put things together")

    How does Turkey represent the European Market when its not even a member of the EU.

    Wiki calls it"is a Eurasian country located 97% in Asia (mostly in the Anatolian peninsula) and 3% in East Thrace in Europe.:

    Geographically you're right, but Turkey sees itself as more European than Asian. That's why you see Turkey trying to get into the European Union. It's not part of any Asian trade bloc. It is also a Nato member and particupate in European games. Turkey is considered to be part of Europe, when purchasing travel insurance.

    In short, Turkey is more European than Asian.

    Asia Times Online :: Erdogan leads Turkey - and the Middle East

    No its much more complicated than that, though historically Turkey has leaned towards the west to the point of being a founding member of NATO, there has been a backlash against the westernizing nationalist movement as Turkey has moved to being once again a more regionally oriented sort of foreign policy.

    Also being a member of the EU is unlikely, those attempts to join have been rejected and there is alot of prejudices against a muslim nation.

    China Debuts a Drone at Robotics Show - WSJ.com

    "China Debuts a Drone at Robotics Show
    By NATHAN HODGE
    AUGUST 18, 2011

    China made its debut this week at the world's largest robotics trade show when a Shenzhen-based firm showcased its F50, a small drone with a high-definition video camera that a company brochure billed as a tool for monitoring protests, or responding to building fires.


    AEE Technology's F50 drone was shown at the world's largest robotics trade show in Washington on Tuesday. (Credit: Charlie Shoemaker for The Wall Street Journal)

    The appearance of AEE Technology Co.'s relatively small, short-range drone—about the size of a pizza pan—in the drone market underscores the burgeoning international competition in the market for unmanned aerial vehicles and military robots.

    State-run and private Chinese companies have invested heavily in recent years in developing drones both for export and for China's military and domestic security needs.

    Western defense officials and experts were taken by surprise in November, when at least 25 Chinese drone models were on display at an air show in south China. Several models were also shown at an exhibition of police and antiterrorism equipment in Beijing in May.

    "The market for military robotics has gone global, and China is looking to be a major producer and exporter in that market, just like the U.S.," said P.W. Singer, the author of "Wired for War," a book about the revolution in military robotics.

    China's investment in new military technology, including the recent launch of an aircraft carrier and the development of a stealth jet, has prompted concern in U.S. military circles. Military analysts have suggested that China is focused on capabilities that could threaten U.S. military vessels in a confrontation over Taiwan. The most recent Defense Department report to Congress on China's military capabilities notes Beijing's push to develop longer-range unmanned aircraft, including armed drones, "expands China's options for long-range reconnaissance and strike."

    But AEE's information brochure—which shows an overhead image of protesters hemmed in by riot police, as well as a building on fire—suggests a similarly strong interest in domestic security.

    AEE was the first Chinese company to exhibit its wares at Unmanned Systems North America, an annual exposition in Washington that features robotic hardware from around the world. In a small booth on the edge of the showroom floor, Wendy Wei, the firm's overseas sales department manager, said the company was looking to drum up international sales—and potential orders from military and police customers.

    "We had a customer yesterday who wants to use it to survey ground for the mining industry," she said. "Anywhere you need someone to do detecting or you need to take videos in a place that human beings cannot go you can use it, so it's a huge market actually."

    Michael O'Hanlon, a defense expert at the Brookings Institution in Washington, said China's interest in developing unmanned aircraft as a tool for policing crowds or responding to emergencies was "totally understandable, and legitimate."

    Broadly speaking, Mr. O'Hanlon said China lagged behind the U.S. in conventional military power, but added that China was "quick in reacting to opportunities, particularly in the smaller weapons areas."

    While China's progress on military drones is of concern to the U.S. and Israel and could worry China's neighbors, its development of drones such as AEE's F50 could also have implications for other countries that have sought to acquire drones not just for military purposes but for police surveillance and antiterrorist operations.

    The U.S. currently dominates the robotics industry and has made drones a centerpiece of its military arsenal. That its drone technology far outstrips that of its rivals was underscored by other equipment on display at the show, such as the A160 Hummingbird, a full-sized robotic helicopter developed by Boeing Co., or a self-driving seven-ton truck being developed by Oshkosh Corp. unit Oshkosh Defense.

    In April, a small robot made by U.S.-based iRobot Corp. was used to explore a reactor building at Japan's crippled Fukushima Daiichi nuclear plant. A Global Hawk, a high-flying pilotless spyplane made by Northrop Grumman Corp., was used to survey the damage above the plant. In Libya, the U.S. military has sent armed Predator drones, made by General Atomics Aeronautical Systems Inc., to strike targets in Libya.

    As competition heats up, U.S. defense executives are increasingly complaining that export controls are making it harder to compete internationally. In a keynote address at the convention Wednesday, Wes Bush, Northrop's CEO, complained that the U.S. export-control regime, which treats unmanned aircraft as extremely sensitive military hardware, made it hard to compete for global customers.

    "Today's export restrictions are hurting this industry in the U.S. without making us any safer," he said. "And they could cause the U.S. to relinquish to other nations ultimately its lead in these technologies."

    Mr. Bush compared the situation to earlier U.S. restrictions on the sale of communications satellites, which spurred other countries to develop their own technologies.

    The Obama administration last year kicked off an effort to overhaul and streamline the system that governs the export of weapons and commercial products that have a potential for military use. The initiative was billed as a way to boost the competitiveness of U.S. manufacturing and technology sectors.

    Kenneth Juergens, a vice president for Oshkosh Defense, said export restrictions made it more difficult to do business internationally, even as U.S. companies look to markets abroad to offset declining U.S. defense budgets. "We need help to get some of those barriers moved or at least streamlined so the approval process moves faster," he said.

    U.S. export controls on things like drones are also a subject of frustration for long-standing customers of U.S. military hardware. Yousef Al Otaiba, the ambassador of the United Arab Emirates to the U.S., said that unmanned aircraft were a "very, very tightly controlled technology" that was pushing countries to develop their own domestic technology...."

    Hisense Group Unveils First Personal Intelligent TV In China - ChinaTechNews.com - The Technology Source for the Latest Chinese News on Internet, Computers, Digital, Science, Electronics, Law, Security, Software, Web 2.0, Telecom, and Wireless Indust

    The Chinese electronics and information industry group Hisense has announced in Beijing that following the start of its strategic transformation to the intelligent product sector, the company has launched its first personal intelligent TV product named I-TV in China.

    The product will be officially put into the market on September 26, 2011 and the price has not yet been decided.

    According to Hisense, unlike the currently popular tablet computer, I'TV is firstly a television. It can also be recognized as a tablet computer with a TV chip.

    As an intelligent TV, I-TV features Hisense's hardware device to receive cable TV signal and then transmit it to other screens like smartphone. Meanwhile, I-TV can search videos on the Internet and transmit them to the TV screen in the drawing room.

    As a tablet computer, I-TV can realize functions such as reading, picture sharing, mobile office, gaming, and Internet surfing. So far, I-TV has over 4,000 applications and the number will soon reach 10,000.

    Zhou Houjian, chairman of Hisense Group, said that I-TV is the result of coordination by many companies under the group. It is the first intelligent product after the start of the group's new strategy and he hopes the product can become a new opportunity of the entire color TV industry in China.

    In May 2011, Hisense launched its "intelligentization strategy" and announced its fully entry into the intelligent industry to establish an intelligent multimedia ecological chain. To promote the smooth implementation of the new strategy, Hisense set up a new intelligent industry promotion department, which is led by Wang Zhihao, vice president of Hisense Group.

    "Taiwanese researchers make nanotechnology breakthrough
    By Yen-yu Huang and Christie Chen
    2011/08/18 21:41:42

    Taipei, Aug. 18 (CNA) Researchers from National Tsing Hua University have made a discovery in nanotechnology that could advance techniques in preserving human stem cells, tissue and other biological samples, the leader of the team that conducted the research said Thursday.

    Team leader Chiang Yun-wei, an assistant professor of chemistry at the university, said the group discovered that mesoporous materials used as a chemical catalyst provide a better environment for the study of protein structures at extremely low temperatures than traditional materials.

    With the use of an advanced electron spin resonance (ESR) technique, the researchers found that biomolecular or protein structures are better preserved and more clearly observed in mesoporous materials than in traditional materials, said Chiang.

    They arrived at their conclusion after adding powder-form mesoporous materials into water in which proteins were being observed, and studying the interaction between the proteins and water molecules in the mixture.

    Even if the temperature is brought down to minus 223 degrees Celsius, the resulting water mixture remains in liquid form, leaving the protein structures undamaged, Chiang told CNA.

    Protein structures and the interaction between proteins and water molecules are best observed at very low temperatures as they slow down molecular movements.

    Chiang said mesoporous material could be used in the future to improve techniques for preserving human tissue, including stem cells, or other biological samples, and help scientists preserve the samples for longer periods.

    The research, conducted by Chiang and three of his graduate students, was published online Aug. 15 on the website of the Proceedings of the National Academy of Sciences of the United States of America."

    It is not a coincidence that the world's top three supercomputing powers are Japan, China, and the United States. There is a strong correlation between the size of a country's economy (e.g. U.S., China, and Japan as world's top three) and its supercomputing power.

    BEIJING - Chinese scientists are charting a new roadmap for the country's independent research into building the fastest supercomputer in 2020.

    "China is preparing to work on a supercomputer with a capacity of 100 petaflops by 2015 and try to produce the first exascale computer in 2020," said Hu Qingfeng, deputy chief designer of Tianhe-1A, one of the world's top 10 fastest supercomputers.

    "We have kicked off the research of some core technologies and manpower cultivation for the plan," Hu, a professor at the National University of Defense Technology (NUDT), told China Daily.

    Exascale computing is an attempt by scientists to take computing beyond the current petascale. If achieved, it will represent a thousandfold increase on that scale.

    The challenges in core techniques include the performance of central processing unit (CPU), interconnection network, programming, energy management and system fault tolerance, he said.

    Tianhe-1A was ranked No 1 in November last year by Top500, an organization that collates information on high-performance computing.

    The capacity of Tianhe-1A is 2.57 petaflops, or 2.57 quadrillion calculations a second, which allows researchers to solve equations with far more variables, making results more accurate.

    The challenges in developing supercomputers not only include technology breakthroughs, but also the promotion among users who usually prefer the old systems they are used to operating, said Lu Yutong, a professor at NUDT and a member of the Tianhe team.

    "In a move to promote supercomputers' application among users, we need to better understand their practical demand," she said.

    The application of Tianhe-1A has won positive feedback from about 100 users in fields such as seismic science, meteorology, medicine, commercial design, construction and manufacturing.

    For example, Feoso Oil needs more than six months to get oil data analysis on a 10-square-kilometer piece of land with a depth of 5 km. However, after entering their equation into Tianhe-1A, the results come out in 16 hours, Hu said .

    In 1978, then-Chinese leader Deng Xiaoping chose NUDT as one of the major institutions to develop China's own supercomputer. Five years later, the college produced its first supercomputer, Yinhe-I. It could perform 100 million calculations a second.

    The next target for the Tianhe-1A team is to build a machine that can perform tens of petaflops per second, as well as developing new CPUs and graphics processing units (GPUs).

    Although the supercomputer uses the 2048 FT-1000 CPUs developed by NUDT, it largely runs on the 14,336 CPUs made by Intel, the US chipmakers, and 7,186 GPUs from Nvidia, also based in the US."

    I removed some of the blue tint from SiegeCrossbow's J-20 photograph, but the improvement was not significant enough to warrant a new post in the J-20 thread. Since I'm here, I might as well throw it into this post.

    TSMC transitions to 28nm and 3D chip stacking technology

    Apple A6 Chip in Early Production Stages at TSMC

    "Apple A6 Chip in Early Production Stages at TSMC
    8:00 PM - August 21, 2011 by Marcus Yam -
    source: Tom's Hardware US

    TSMC could score yet another contract for a fancy chip.


    Apple A4 iPad CPU

    Samsung is Apple's chip partner with its ARM-based A4 and A5 that have been the brains of the latest iPod touch, iPhone, iPad and Apple TV devices. Of course, the two companies aren't friends in the legal realm right now, so perhaps Apple is just looking for a new friend with a factory.

    The Taiwanese Economic News reports that Taiwan Semiconductor Manufacturing Co., Ltd. (TSMC) has allegedly started trial production of Apple's A6 chip, which will likely be used in future generations of Apple mobile devices.

    TSMC is lending its 28nm process with 3D chip stacking technology to Apple's A6 chip, with plans to be taped out in Q1 2012. The A6 could hit real products as soon as Q2.

    Sadly, there are not any details yet regarding the chip, but hopefully it'll give Nvidia's quad-core Kal-El a run for its money. Yay for competitive progress, right?"

    Nvidia: We Are Well Prepared for 28nm Process Technology - X-bit labs

    "Nvidia: We Are Well Prepared for 28nm Process Technology.
    Nvidia: We Have Working 28nm Silicon
    [08/11/2011 11:26 PM]
    by Anton Shilov

    Nvidia Corp. said it had learnt the lessons with 40nm process technology and would not repeat its mistakes with the 28nm fabrication process. The company spent time on learning the peculiarities of the 28nm manufacturing technology from Taiwan Semiconductor Manufacturing Company and already has working 28nm chips.

    "We are far better prepared for 28nm than we were for 40nm. Because we took it so much more seriously. We were successful on so many different nodes for so long that we all collectively, as an industry, forgot how hard it is. So, one of the things that we did this time around was to set up an entire organization that is dedicated to advanced nodes. We have had many, many tests chips run on 28nm, we have working silicon," said Jen-Hsun Huang, chief executive officer of Nvidia.

    TSMC's 40nm manufacturing process was plagued with low yields conditioned by problems with the technology itself, manufacturing issues and design errors. Nvidia started to develop its 40nm lineup without knowing about the potential issues and when it ran into a set of unexpected problems it had to delay launch of its key-products based on Fermi architecture. With 28nm process technology, the company seems to be better prepared.


    Taiwan Semiconductor Manufacturing Company (TSMC) fabrication facility

    "[Our experience with 28nm] is looking really good, it is looking much better than our experience with 40nm. It is just a comprehensive, across-the-board engagement between TSMC and ourselves making sure that we are ready for production ramp when the time comes. So I feel really good about 28nm," said Jen-Hsun Huang.

    Nvidia said earlier this month that it plans to test-drive its next-generation Kepler graphics processing unit (GPU) this year and introduce the new chips commercially in 2012.

    Kepler is Nvidia's next-generation graphics processor architecture that is projected to bring considerable performance improvements and will likely make the GPU more flexible in terms of programmability, which will speed up development of applications that take advantage of GPGPU (general purpose processing on GPU) technologies. Some of the technologies that Nvidia promised to introduce in Kepler and Maxwell (the architecture that will succeed Kepler) include virtual memory space (which will allow CPUs and GPUs to use the "unified" virtual memory), pre-emption, enhance the ability of GPU to autonomously process the data without the help of CPU and so on."

    AMD to "Kill" APU in 2012; Move to SOC with 28nm Krishna and Wichita - Bright Side Of News*

    "AMD to "Kill" APU in 2012; Move to SOC with 28nm Krishna and Wichita
    by Theo Valich

    ...

    AMD Fusion Roadmap for 2012: 32nm Trinity will be made by GlobalFoundries, while 28nm Krishna and Wichita come out of TSMC

    Instead of being a long-term architecture, APU with its CPU, GPU and memory controller bolted together will only fly for a generation or two, before AMD releases a fully-blown SOC (System-on-a-Chip) design. With the low-power Bobcat core, which targets entry-level computing devices such as tablets, netbooks and low-end notebooks and desktops, the APU-to-SOC shift is going to happen with the second generation already.


    AMD Krishna and Wichita SOC designs: Future C-, E- and Z-Series APUs, all fitting inside the 18W TDP bracket. You can expect further decreases, to the tune of 8W and 16W SOC designs, even though Krishna and Wichita incorporate more parts in silicon

    The 2012 platform is codenamed "Deccan" and will consist out of Krishna and Wichita processors (successors of Ontario and Zacate, the current C-, E- and Z-Series APUs). Both designs will be manufactured using 28nm process over at TSMC, featuring up to four Bobcat cores, up to 2MB of L2 cache and naturally, a support for Turbo core mode.

    Both Wichita and Krishna will pack 25% boost in graphics processing department, with the GPU design being brought up to Northern Islands standard, supporting UVD 3 with Secure Asset Management Unit (SAMU) and further improvements to multimedia standards (read: hardware acceleration for more codecs and technologies such as stereoscopic 3D).

    The big change is the SOC part of the silicon: Yuba Fusion Controller Hub is moving onto the APU silicon, making these parts first SOC designs coming out of AMD stable.

    Yuba FCH supports single PCIe x16 and four x1 ports, DVI, HDMI and Analog VGA, SATA 6Gbps, HD Audio, USB (dedicated 2.0 and 3.0 ports) legacy PCI, LPC and SPI. As you can imagine, all of these changes cannot fit inside the current Socket FM1, which is the main reason why Wichita and Krishna will utilize Socket FM2 in a discrete or embedded (BGA - Ball Grid Array) form factor.

    It is expected that Trinity, the 32nm Bulldozer-based APU will continue to use Socket FM1 and evolve from APU to a SOC design in 2013.

    Late 2012 and early 2013 are shaping up to be the time of SOC: 22nm Intel Atom Z Series, 28 and 32nm AMD Fusion, NVIDIA Project Denver, Qualcomm Snapdragon 8974, TI OMAP5 and many more.

    To us, it looks that AMD has the upper hand, with NVIDIA's ability to surprise. Qualcomm Snapdragon 8974 slipped by more than two quarters and naturally, Intel can always come in with 22nm Medfield and wipe the floor with unconcerned competition."

    Re: News on China's scientific and technological development.

    A bit of bad news here...

    Chinese orbiter fails to enter designated orbit|Sci-Tech|chinadaily.com.cn

    JIUQUAN, Gansu - China's experimental satellite, which was launched by the Long March II-C rocket Thursday, failed to enter the designated orbit due to a rocket malfunction.

    The rocket carrying the SJ-11-04 orbiter experienced problems during flight after it was launched from the Jiuquan Satellite Launch Center at 5:28 pm Beijing Time in Northwest China's Gansu province.

    Beijing News cited an unnamed military observer as saying the malfunction stopped the rocket from entering a planned altitude.

    "We don't know when the problem occurred, so it will be hard to find out the cause," the observer said, adding the orbiter may land in China's territory if the malfunction happened at the primary period of the launch and may drop into the Pacific Ocean if the malfunction happened late.

    The failure, however, won't affect the launch of Tiangong-1, which will be carried by a different rocket Long March II-F, the observer said.

    Tiangong-1 was designed as a platform that will dock with an unmanned spaceship, Shenzhou VIII, for the country's first space-docking mission later this year.

    It is the first time the Long March II-C rocket failed a mission, Beijing News said. The specific cause of the failure is being analyzed.
