eMAG is a 64-bit 32-core ARM server microprocessor introduced by Ampere in 2018. Fabricated on TSMC's 16FF+ based on the Skylark microarchitecture, this processor operates at 3 GHz with a turbo frequency of up to 3.3 GHz and 125 W TDP. This processor supports up to 8 channels of DDR4-2666 ECC memory.

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.
