Template:mpu PEZY-SC (PEZY Super Computer) is second generation many-core microprocessor developed by PEZY in 2014. PEZY-SC contains 2 ARM926 cores (ARMv5TEJ) along with 1024 simpler RISC cores. Operating at 733 MHz, the processor is said to have peak performance of 3.0 TFLOPS (single-precision) and 1.5 TFLOPS (double-precision). PEZY-SC was designed using 580 million gates and manufactured on TSMC's 28HPC+ (28 nm process). The PEZY-SC is used in a number of TOP500 & Green500 supercomputers as the world's most efficient supercomputers.

Overview
- See also: PEZY-1
The PEZY-SC (SC for "Super Computer") is PEZY's second generation microprocessors which builds upon the PEZY-1. The chip contains exactly twice as many cores and incorporates a large amount of cache including 8 MB of L3$.
In June of 2015, PEZY-SC-based supercomputers took all top 3 spots on the Green500 listing as the 3 most efficient supercomputers. PEZY-SC powers Shoubu (1,181,952 cores, ? kW, 605.624 TFlop/s Linpack Rmax), and Suiren Blue (262,656 cores, 40.86 kW, 247.752 TFlop/s Linpack Rmax), and Suiren (328,480 cores, 48.90 kW, 271.782 TFlop/s Linpack Rmax) supercomputers (ranked 1, 2, and 3 respectively).
Architecture
The PEZY-SC microprocessors is made of 4 blocks called "Prefectures". The Prefecture contains 2 MB of L3$ enclosed by 16 smaller blocks called "Cities". Each City is made of 64 KB of L2$, a number of special function units, and 4 smaller blocks called "Villages". A village is a block of 4 execution units. For ever 2 execution units there are 2 KB of L1d$.
Processor Element (PE)
The PE are the individual execution cores.

Cache
PEZY-SC's cache is separate from the ARM926's cache which has an L1$ of 32 KiB (2x) and 64 KiB L2$ (shared).

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
