China's 64bit Homegrown CPU
An anonymous reader writes: "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." The Godson processor line has generally been called Dragon by the Western press.

To all you genius programmers: you're good. But are you good enough to outhack half a dozen Chinese guys working for half your salary?
I predict that within 10 years, half the US programming market will have gone to these overseas firms.
Been there, done that.

Maybe the could just have used the extra space for a proper move instruction so R0 is freed.
The MIPS architecture already has a proper 'move' instruction without using r0: r12 = r8 | r8, or r12 = r8 | 0 (zero specified as immediate). The r0 is frozen at 0 so you can do negations (for which ARM uses 'rsb' or reverse subtraction) and other things where zero must be the first argument.
Will I retire or break 10K?
Actually, MIPS asm _is_ an open standard and they were careful to not use the few instructions that were covered by patents.
From the sound of it, the Godson chips will be lower powered in terms of performance to current US chips. However, I find the energy consumption to be very attractive. Ie, 5 watts and 10 watts for 266Mhz 500 Mhz respectively. Scaling up linearly, that's still just 20 watts of power consumption for a 2Ghz chip.
But what I'm thinking is that China is aiming for is low cost and low power consumption chips. Ie, can be used in portable hardware and/or massively parallel setups.
Granted, they can't SMP the chips in hardware, but with a Linux cluster of these, they could quite readily setup a powerful computing cluster.
Personally, I'm glad that they are designing their own chips. It would be nice to see more competition outside of just the big two.
The way I see it, if they produce these chips at low prices($15-$50), at such low power consumption levels, I could easily see myself building many small nodes of them. Maybe now, I can POVray just ever so faster... :)
