Template:mpu R-Car H2 is a high-end embedded nona-core SoC for the automotive industry introduced by Renesas in early 2013. The H2 incorporates four Cortex-A15 cores operating at 1.5 GHz, four Cortex-A7 cores operating at 1 GHz, and one SH-4A core operating at 780 MHz for real-time processing. This SoC incorporates Imagination's PowerVR G6400 GPU operating at 550 MHz and supports up to dual-channel DDR3-1600 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.
