APM883408-X2 is a 64-bit octa-core ARM server microprocessor designed by AppliedMicro and introduced in 2014. Fabricated on TSMC 28 nm process based on the Shadowcat microarchitecture, this processor has eight custom ARMv8 cores operating at up to 2.4 GHz and supporting up to 256 GiB of quad-channel DDR3-1866 memory.
Cache[edit]
- Main article: Shadowcat § Cache
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. |
