R-Car H1 is a high-end embedded penta-core SoC for the automotive industry designed by Renesas and introduced in 2011. The H1 features 5 cores, four Cortex-A9 cores operating at 1 GHz and an additional SH-4A core operating at 800 MHz intended for real-time processing multimedia engine (MME). This chip incorporates Imagination's PowerVR SGX543-MP2 GPU. The H1 supports up to 2 GiB of dual-channel DDR3-1066 memory.

Announced in late 2011, Renesas expected mass production begin in December 2012 with a peak rate of 100,000 units per month by December 2013.

Cache

[Edit/Modify Cache Info]

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.
