FeiTeng (processor)

The FeiTeng (飞腾, fēiténg) - several computer central processing units designed and produced in China.[1]

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.[2] 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.[3]

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.[4]

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. [5]

The Tianhe-1A supercomputer uses 2,048 FeiTeng 1000 processors.[6] Tianhe-1A has a theoretical peak performance of 4.701 petaflops.[5][7] The FeiTeng-1000 is an eight-core processor based on the SPARC system and is used to operate service nodes on the Tianhe-1.[1][5]

It has been speculated that FeiTeng used the work of the OpenSPARC project.[8]

Galaxy FT-1500

Tianhe-2 supercomupter uses 4096 processors Galaxy FT-1500 with 16 cores, Sparc V9 architecture and 65 W TDP. They are made with 40 nm technology, processor cores work at 1.8 GHz[9] Peak performance of FT-1500 is 115-144 GFLOPS; every core may execute up to 8 interleaving threads and supports 256-bit wide SIMD vector operations including Fused Mul-Add (FMA). Cache of this SoC works at 2 GHz frequency, there are 16 KB L1i, 16 KB L1d, 512 KB L2 per core, and shared 4 MB L3 cache. L3 cache has 4 segments (1 segment per block of 4 cpu cores), each of 1 MB with 32-way associative. Cache uses directory-based cache coherency protocol. FT-1500 also has:[10]
