The Chinese people have a "core": the government defines the CPU framework standard

CPU architecture China Godson

Last month, Chinese officials launched a program aimed at defining a national processor architecture. If the project succeeds, any project seeking government funding may require the adoption of such a framework, such as computers and smartphones.

Consider at least five existing processor architectures that serve as the basis for the above criteria. The program can also be used to define its own instruction set (ISA) or extend the existing instruction set. In March, the first meeting of China's national command architecture program was held, which was presided over by the Ministry of industry and information.

Representatives from about 20 Chinese organizations attended the conference, including HUAWEI, ZTE, and representatives of some research institutions.

This is one of several recent Chinese leaders in charge of the Chinese, aims to establish their own standards and intellectual property rights, get rid of the payment of royalties to foreign enterprises situation. China has developed a number of standards, ranging from CD/DVD player to surveillance video system in many fields.

China-based development of the third generation of mobile communication standard TD-SCDMA, is by far the most prominent results. Although the results of this plan is now good or bad, but the strong support of the market. China's largest operator China Mobile has begun to actually test 4G standard TD-LTE.

China has been trying to develop its own processor standards over the years, launched mainly based on the MIPS core Godson. Observers have different views on whether China's latest efforts are successful.

"My impression is that" the processor group has chosen a national standard, "said Robert Bismuth, vice president of business development at MIPS Technologies." I actually thought it would happen. "He also pointed out "Godson is indeed used in the government department of the system."

This may be wishful thinking. According to reports, MIPS Technologies operating income decline, ready to sell the company. "China has several MIPS-based cores, but MPS will eventually close and sell its IP and patents," said an executive executive who asked anonymity.

Its Chinese companies have access to ARM and PowerPC kernel license. He said that ARM for some Chinese enterprises is too expensive, they want a lower cost of the program. "We can not only have a choice of ARM, so PowerPC got a chance."

The Chinese executive said the license to get the ARM high-end Cortex A9 core at least 5 million US dollars, which prompted at least one Tablet PC project selected PowerPC and Linux, and gave up ARM and Andrews.

ARM executives are skeptical about China's processor plans. "We are certainly aware of this plan," said Tudor Brown, president of ARM, in an e-mail. "This is not news, and the program has been discussed for many months."

“We understand that China has its own desire for ISA, we will continue to provide cooperation and discuss with the relevant key personnel to achieve an excellent solution, "Brown said," the key issue is not ISA itself, but ISA around the ecosystem The "He stressed the size of the ARM ecosystem.

"While defining an ISA is a relatively short activity, it takes a long time to build and deploy a viable ecosystem," Brown added.

In fact, ARM not only in the mobile system has a dominant position, but also in the Chinese chip manufacturers also have a strong influence. According to "EE Times" published in late 2011 on a Chinese chip design company's report, ARM in China has more than 34 licenses, and MIPS is more than 20.

In the computer world, Intel and x86 architectures dominate all system sales, including in the Chinese market. Faced with such powerful giants, it is very difficult to build an ecosystem for a new PC or mobile processor architecture.

However, MIPS 'Bismuth said the Chinese government leaders "hope that China and the West are on an equal footing. "They want to build a common software ecosystem," he says. "The only way to do this is to use a common ISA."

"They are willing to get a license for the existing architecture and then get rid of this architecture, they are not reluctant to pay," Bismuth said
