Microarchitecture |
APM883208-X2 is a 64-bit 32-core ARM server microprocessor designed by AppliedMicro and announced in 2016. Fabricated on TSMC's 16 nm process based on the Skylark microarchitecture, this processor features 32 custom ARMv8 cores operating at up to 3 GHz with a TDP of 125 W. This chip supports up to 1 TiB of octa-channel DDR4-2666 memory.
This processor was only sampled and never made it to general availability. Ths IP was eventually sold to Ampere Computing which re-introduced the chip under the eMAG 8180 name.

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. |
