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.

Cache[edit]

PEZY-1's cache is separate from the ARM926's cache which has an L1$ of 16 KiB (2x) and no L2$.

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.
