Helio P20 (MT6757) is a 64-bitocta-coreARMLTE system on a chip designed by MediaTek and launched in late 2016. This SoC, which incorporates eight Cortex-A53 cores and is manufactured on TSMC's 16 nm process, operates at up to 2.3 GHz and supports up to 6 GiB of dual-channel LPDDR4X-3200 memory. This chip incorporates the Mali-T880IGP operating at 900 MHz. This SoC has a modem supporting LTE User Equipment (UE) category 6.
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.
