Godson-2D1 (龙芯2D1) is a 64-bit MIPS performance processor developed by ICT and later Loongson for desktop computers.The Godson-2D1 operates at up to 800 MHz consuming up to 6 W. This chip was manufactured on STMicroelectronics' 0.13 µm process. This chip reached tapeout on January 6, 2005.
Loongson has claimed the Godson-2D has reached the performance level of 1.5 GHz PIV based on their SPECint2000 scores.
Cache[edit]

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. |
