FeiTeng (processor)
The FeiTeng (飞腾, fēiténg) - several computer central processing units designed and produced in China.〔''U.S. says China building 'entirely indigenous' supercomputer'', by Patrick Thibodeau
Computerworld, November 4, 2010 ()〕
FeiTeng-1000 is third generation CPU from the YinHeFeiTeng (银河飞騰, YHFT) family. This CPU family has been developed by team directed by NUDT Prof. Xing Zuocheng.〔http://www.ee.ust.hk/ece.php/event/detail/671 «Prof. Xing and his team developed FT-1000/1000A/1500 series multi-core processors, the world’s first general-purpose 64-bit stream processor for scientific computing, and the world’s first CPU compatible with Intel Itanium processor.»〕 The first generation was binary compatible with the Intel Itanium 2. The second generation, the FT64, was a system on a chip with CPU and 64-bit stream processor. FT64 were used in YinHe (银河) supercomputers as accelerators.〔http://www.ece.ust.hk/ece.php/event/detail/702〕
== FeiTeng-1000 ==
FeiTeng-1000 is manufactured with 65 nm technology and contains 350 million gates. Its clock frequency is 0.8–1 GHz. It is compatible with SPARCv9 instruction set architecture.〔http://english.people.com.cn/90001/90778/90860/7331502.html〕
Each chip contains 8 cores and is capable of executing 64 threads. There are 3 HyperTransport channels for coherent links, 4 DDR3 memory controllers and a 8x PCIe 2.0 link.

The Tianhe-1A supercomputer uses 2,048 FeiTeng 1000 processors. Tianhe-1A has a theoretical peak performance of 4.701 petaflops.〔''The TianHe-1A Supercomputer: Its Hardware and Software'' by Xue-Jun Yang, Xiang-Ke Liao, et al in the ''Journal of Computer Science and Technology'', Volume 26, Number 3, May 2011, pages 344-351 ()〕 The FeiTeng-1000 is an eight-core processor based on the SPARC system and is used to operate service nodes on the Tianhe-1.〔〔
It has been speculated that FeiTeng used the work of the OpenSPARC project.〔http://www.prace-project.eu/IMG/pdf/d8.4_1ip.pdf page 41〕
