Template:mpu QorIQ P1012 is a 32-bit embedded POWER microprocessor introduced by Freescale in late 2009. This networking/embedded processor, which is based on the e500 microarchitecture and is fabricated on a 45 nm SOI process, operates at 533 MHz (with higher frequencies offered later on) and supports 32-bit DDR3-800 memory.

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.
