Template:mpu SC2A11 is a 64-bit tetracosa-core ARM system on a chip designed by Socionext for low-power servers and cloud/IoT edge computing. This chip, which incorporates 24 ultra-low power Cortex-A53 cores, operates at 1 GHz and supports up to DDR4-2133 EEC memory.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

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.
