QorIQ P1020 - Freescale
Template:mpu QorIQ P1020 is a 32-bit embedded dual-core POWER microprocessor introduced by Freescale in 2008. This networking/embedded processor, which is based on the e500 microarchitecture and is fabricated on a 45 nm SOI process, operates at 1.2 GHz and supports 32-bit DDR2/3 memory.
Cache
- Main article: e500 § Cache
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. |
