Hi1616 is a dotriaconta-core 64-bit ARM server microprocessor introduced by HiSilicon in mid-2017. Fabricated by TSMC on a 16 nm process, this chip incorporates 32 Cortex-A72 cores operating at 2.4 GHz. The Hi1616 supports up to 256 GiB of quad-channel DDR4-2400 memory.

Cache

[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.
