K3V2E is a 32-bit quad-core mobile ARM microprocessor introduced by HiSilicon in 2013. This chip, which is fabricated on a 40 nm process, incorporates four Cortex-A9 cores operating at 1.5 GHz. The K3V2 integrated Vivante's GC4000 (16 cores) IGP and supports up to 2 channels of LPDDR2-900 memory. The K3V2E is an enhanced version of the K3V2, although the exact changes are not well-documented.

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.
