R-Car H3 is a 64-bit nona-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 dual-core lock-step Cortex-R7 for real-time processing. This chip supports up to quad-channel LPDDR4-3200 memory. This chip incorporates the Imagination's PowerVR GX6650 GPU.

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.

[Edit/Modify Cache Info]

hierarchy icon.svg
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.
