Template:mpu R-Car H1 is a high-end embedded penta-core SoC for the automotive industry designed by Renesas and introduced in 2011. While mass production was scheduled to begin in December 2012, it's unknown if that stage was ever actually reached. 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 chips incorporates Imagination's PowerVR SGX543-MP2 GPU. The H1 supports up to 2 GiB of DDR3-1066 memory.

Cache

Main article: Cortex-A9 § 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.
