Template:mpu R-Car H3 is a 64-bit deca-core ARM SoC designed by Renesas for the automotive industry and introduced in 2016. The H3 incorporates four Cortex-A57 cores, four Cortex-A53 cores, and a two Cortex-R7 cores for real-time processing. This chip supports up to quad-channel LPDDR4-3200 memory. This chip incorporates the Imagination's PowerVR GX6650 GPU.

This model is an SiP variant of the H3 which include the DDR memory on-package.

Samples for the H3 were available starting December 2015 with Renesas expecting mass production to begin in March 2018 and reach a volume of 100,000 units per month in March 2019.

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.
