Made in China: The Godson Processor

Not to be left behind in the microprocessor business, China is working on a low-power MIPS-based processor with x86 emulation.

PALO ALTO, Calif. -- The 20th annual HOT CHIPS conference at Stanford University is an academic show, not a vendor-driven one. That means the biggest guns share the stage with the littlest pistols; and it gives the little guys a chance to shine.

In this case, a Chinese processor project found itself sandwiched between presentations from AMD and Intel, with its own unique story to tell.

The Chinese Academy of Sciences is a nationally-funded institution with five main areas of focus, one of which is technology. Within that area is the Institute for Computing Technology, which designed the Godson processor, a project that began in 2001.

China decided to support microprocessors because it has come to realize CPU design is important and one of national strategic importance, said Zhiwei Xu, chief technology officer and a professor at the institute during his speech here.

Now on its third generation of Godson, the ICT has managed to triple performance with each generation, although he admitted it still has a long way to go to close the gap with giants like Intel (NASDAQ: INTC), AMD (NYSE: AMD) and IBM (NYSE: IBM), but added "we are doing our best to join the international community."

Godson-2 and 3 are scalable 64-bit single core processors built on 90 nanometer design. They are instruction-compatible with the MIPS III processor architecture, and Xu said the company has a license from MIPS for such compatibility. The operating system of choice for Godson-powered computers, said Xu, is Linux.

The current Godson-2 generation, E and F, are both 1Ghz processors, consuming from 3 to 7 watts of power. Godson-2E has an on-chip DDR (define) controller while Godson-2F has an on-chip DDR2 (define) controller. A Godson-2G and –2H are also planned for computers as well as System on a Chip (SoC) designs.

Xu then introduced the Godson-3 design, which will be a four-core, 1.0Ghz chip on a 65nm process design and consume just 10 watts of power. The core will be reconfigurable into one of two purposes and it will have on-the-fly x86 binary translation, which Xu said would be 10 times as fast as software-only emulation.
