PEZY-1 was a first generation many-core microprocessor developed by PEZY in 2012. PEZY-1 contains 2 ARM926 cores (ARMv5TEJ) along with 512 simpler RISC cores. Operating at 533 MHz, the processor is said to have peak performance of 533 GFLOPS (single-precision) and 266 GFLOPS (double-precision). PEZY-1 was designed using 220 million gates and manufactured on TSMC's 40 nm process.
The PEZY-1 is used for image processing devices and various medical instruments. In 2014 PEZY introduced their second generation many-core processor, the PEZY-SC, with twice as many cores and formed the basis for the PEZY-SCx family.
PEZY-1's cache is separate from the ARM926's cache which has an L1$ of 16 KiB (2x) and no L2$.
PEZY-1 Quad PCI Board
PEZY has developed a Quad-PEZY-1 PCI board for their microprocessors which has 4 PEZY-1 for a total of 2,048 PE cores (along with 8 ARM cores). The board is equipped with 64 GiB of memory for a total bandwidth of 200 GB/s. PEZY reports the total computational power for the board to be at 2.56 TFLOPS with a power consumption of 180 Watts.
