R-Car M1A is a mid-range performance embedded dual-core SoC for the automotive industry designed by Renesas and introduced in 2011. The M1A features a single Cortex-A9 core and an additional SH-4A core, both operating at 800 MHz. This chip incorporates Imagination's PowerVR SGX540 GPU operating at 200 MHz. This SoC supports up to 1 GiB of dual-channel DDR3-1066 memory.

Introduced early-2011 with samples available in May 2011. Renesas expected mass production to begin in June 2012.

Cache[edit]

Main article: Cortex-A9 § Cache

[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.
