brejc8's Journal: China's 64bit homegrown CPU

EE Times is reporting on China's BLX IC Design Corp nearing the completion of their first 64-bit CPU. Based on the MIPS instruction set the 500-MHz Godson-2 microprocessor is aimed toward distributed grid computing. To avoid MIPS patent issues, several instructions (unaligned loads and storeds in the 32 bit version) have not been implemented but with the support of over 60 software providers such as Red Flag Linux and the ability to tweak compilers to not use these instructions this should not be a problem. The Godson-1 processor (also patent free) was announced last year and was aimed at the embedded market. Although there are no patent issues MIPS have been known to be very aggressive toward people who try to create compatible systems.
