Template:mpu 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 peach 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.
Cache
PEZY-1's cache is separate from the ARM926's cache which has an L1$ of 16KB (2x) and no L2$.
