R-Car L1 is a performance embedded SoC for the automotive industry designed by Renesas. The L1 features a single Cortex-A9 core operating at 400 MHz. This chip incorporates Imagination's PowerVR SGX531 GPU. This SoC supports up to 1 GiB of DDR3-1066 memory.

  • Note: It's unknown if this model was ever actually released.


Cache[edit]

[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.
