China Releases 2nd generation MIPS Chip
eldawg writes writes with news of the launch of a second-generation Chinese 64-bit MIPS CPU. "The Godson-2 or 'Dragon' went into production last week. News reports indicate that, 'The CPU is 95% MIPS compatible using an unauthorized and unlicensed variation of the MIPS architecture, which is owned by the American company MIPS Technologies...The Godson-2 is pretty much a copy of the MIPS R10000 which makes it on par with 1995 technology.' The Chinese plan on using these chips in consumer electronics for the local market, but one can assume that they will eventually end up in exported electronic goods. I wonder if MIPS Technology will sit idly by when this happens?"
"The Register" has a better write up on this story (sorry guys). Apparently they've managed to get Windows CE, Linux, and VxWorks up and running on the CPU.
As for the patented instruction sets, apparently they aren't used in the chip. (Supposedly that's why it's 95% compatible).
Currently the chip clocks in at 400-500Mhz, but the next generation is going to be around the 1Ghz mark - by which point China is going to be spitting out all manner of sub $200 computers I imagine.
READY.

Interesting bits from those Chinese sites:
- (back in 2003) they're already running Linux on it, with applications such as MP3 audio/mpeg movie playing, Mozilla, OpenOffice, games...
- (back in 2003) Max clock 300MHz, 1-2W power consumption, 1% CPU load for playing MP3, 23% for mpeg movie, SPEC_CPU2000 score of 300
- will reach 1GHz by early 2006
- it will be used in low-cost PC with price RMB1,000
- the 3rd gen of the chip will incorporate multi-core design
