R-Car M3 (SiP - Renesas
} Template:mpu R-Car M3 is a 64-bit hepta-core ARM SoC designed by Renesas for the automotive industry and introduced in 2016. The M3 incorporates four Cortex-A53 cores, two Cortex-A57, and an additional Cortex-R7 core for real-time processing. This chip supports up to dual-channel LPDDR4-3200 memory.
This model is an SiP variant of the M3 which include the DDR memory on-package.

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. |
