applications. The microprocessors have been developed by Tianjin Phytium Technology. The processors have also been described as the YinHeFeiTeng (银河飞騰, YHFT) family. This CPU family has been developed by a team directed by NUDT's Professor Xing Zuocheng.


Initial designs

The first generation was binary compatible with the Intel Itanium 2. The second generation, the FT64, was a

architecture based and 65 W TDP. They are made with 40 nm technology, processor cores work at 1.8 GHz. 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: * Links to connect several processors into NUMA machine * 4 integrated DDR3 memory controllers * 2 PCI-express controllers * 10 Gbit Ethernet ports


FT-1500A

FT-1500A is an ARM64 SoC designed by Phytium, which includes 16 cores of ARMv8 processor, a 32-lane PCIe host, 2 GMAC on-chip ethernet controller and a GICv3 interrupt controller with ITS support.


Future processors

In 2020, Feiteng announced availability of the S2500 processor and a roadmap for the following years.
