Template:mpu Godson-2B (龙芯2B) is a 64-bit MIPS performance processor developed by ICT and later Loongson for desktop computers. Introduced in late 2003, the Godson-2B operates at up to 300 MHz consuming up to 3 W. This chip was manufactured on SMICS' 0.18 µm process and is known as China's first 64-bit microprocessor. This chip reached tapeout on August 13, 2003.
Cache

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. |
