Template:mpu Godson-2F (龙芯2F) is a 64-bit MIPS performance processor developed by ICT and later Loongson for desktop computers. Introduced in mid-2008, the Godson-2F operates at up to 800 MHz consuming 5 W. This chip was manufactured on STMicroelectronics' 90 nm process.

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.
