Weiwu Godson about patents: the moment the Red Army as early

6 21, architect Weiwu Godson wrote the theme article, "buy on the calculation of the structure of authority MIPS consideration" to buy MIPS Godson authorized to make detailed interpretation of the results.

Article, Weiwu wrote, Institute of Computing MIPS structure obtained authorization is permanent, will be free to design a variety of CPU chips, chip manufacturers in the domestic and BCX56-16 datasheet and international flow of films, performance can be constantly upgraded, there is no future Godson development is subject to MIPS big companies. He said the structure of purchased license MIPS little cost, the cost of only a small proportion of total R & D costs, or even much lower than the calculation of the costs for the purchase of EDA tools.

And future branded products in the Godson "MIPS-compatible" label is very easy to get formal recognition of large companies. Cooperation with many manufacturers and BCX56-16 price and Godson Godson was mainly due to the benefits of a MIPS-compatible, STMicroelectronics is one of them. Recently, many multinational corporations began to cooperate with the Godson is also compatible with MIPS as we take the route.

He said, is aimed at self-control, the current licensing model is completely controllable mode, mainly to use the "MIPS-compatible" trademark and BCX56-16 suppliers and access to MIPSs services. Godson of all R & D are independent, in the core technology is not controlled by others. The current CPU market is highly monopolized, the threshold is high, the premise in a controlled, Godson need to unite forces.

Godson article Weiwu will be earlier than the Red Army, think we should adhere to independent innovation, and the premise in a controlled establishment of a broad united front and unite the power is the correct way to victory Godson

The following article details:

MIPS structure on the calculation of the purchase consideration of authorization

1. Godson processors, the development and application situation

CAS Institute of Computing since 2001, the development of Godson processors. After 8 years of accumulation and effort to master the core technology of high-performance processor design and quality, the Godson family of processors to reach the world advanced level (the most recent tape of the quad-core 65nm Godson-3 processor technology, frequency 1GHz, the number of transistors to reach 425 million.)

In recent years, the computing industry by actively exploring the road of Godson and has achieved great success. Godson processors in the military and industrial control, networking, and application of low-cost computers to hundreds of thousands of domain films, the formation of the Godson processor products. Godson CPU, 1 defines its IP for embedded applications, Godson-2 CPU and IP for high-end embedded and desktop applications, multi-core Godson-3 CPU for servers and high-performance machine positioning applications.

Godson processors through the development, CAS Institute of Computing was established to meet the self-developed high-performance general-purpose CPU platform based design; achieved a number associated with the CPU design patent; establish a world-class chip design team, the combination of a number of advanced CPU chip design talent. The successful development of Godson processors, marking the country mastered the core technology of high-performance general-purpose processor, off Chinas information industry has been the foundation of a basic protection of information security.

Under these conditions, the calculation conduct through commercial development and application of Godson CPU time is ripe for promotion. It is authorized through the purchase of MIPS structure carried out in the above context. In addition, in the context of the economic crisis than usual to buy MIPS structure of authority can get better prices.

2. What is the MIPS structure authorized

Godson processor MIPS instruction set selected important reason is because of market considerations. MIPS structure is an open architecture, MIPS company is different from Intel, SUN and IBM, it is not IDM, he does not produce sales of chips, but License to sell and service business, it not only as against other companies like Intel is compatible with the chip, but other manufacturers do support the MIPS compatible chip. Many of the world large companies such as CISCO, SONY, AMD, ATI, NEC, LSI, IDT, and ITE, etc., companies have purchased hundreds of MIPSs License. SGI 90s last century, the company has used to do high-end MIPS workstations and server chips, MIPS chips are now the mainstream of the international high-end embedded CPU on one chip, MIPS 2008, sales of more than 400 million are authorized customer sales MIPS .

MIPS processor core mandate of the License is divided into (CoreLicense) and structural empowerment (ArchitectureLicense) categories. Authorized the purchase of processor cores designed by the MIPS, MIPS-compatible processor core, divided into soft-core and hard core, which is designed by the MIPS processor core. Authorize purchase of the structure is mainly to use MIPS-compatible brands and sharing by joining MIPS compatible Union intellectual property rights, authorization to purchase the structure design of the processor core need for autonomy. Calculations are buying is the structure of the company authorized by MIPS.

Structural empowerment is the core instruction set compatibility, instruction system is the computer hardware to software programming language. For example, "Sixty-six" and "66" expresses the same meaning, but which the world can understand, while the former only know Chinese people can understand. Instruction, too, is a code, a computer language. MIPS instruction compatible with the system can run many of the existing system software and application software. Including Linux, Vxworks and WinCE operating systems support, including MIPS instruction; MIPS is also very rich applications, such as MIPS has put the companys operating system, Google Android ported to the MIPS architecture, which makes devices that can run on MIPS Android, MIPS-compatible license means that the Godson chip platform to support Android and the Android platform using the applications and resources. Therefore, the purchase of MIPS compatible chip Godson authorized to shorten time to market.

Calculations have been completed on the MIPS instruction set patent analysis, in China to achieve a complete MIPS MIPS instruction set the company does not infringe the patent protection of four special instructions. This structure is not authorized to purchase MIPS patents. But without the structure of the company authorized by MIPS, MIPS company will not get the service, Godson processors can not use the "MIPS-compatible (MIPSCompatible)" sign, is not conducive to the promotion of Godson processors. Therefore, the structure of purchased MIPS license, mainly based on expansion of market considerations, does not affect the autonomy of Godson CPU.

3. Purchase benefits authorized by MIPS structure

Godson processor MIPS instruction selection important reason is: relative to their own definition of a new instruction set, MIPS-compatible way to go and explore the market more easily. Godson CPU

development and industrial environment of the goal is to create proprietary information technology infrastructure platform to build Chinas own industrial system of information control to change the kinds of situation in Chinas information industry. In the long run, is authorized to purchase the structure of MIPS has many benefits.

(1) Institute of Computing MIPS structure obtained authorization is permanent, will be free to design a variety of CPU chips, chip manufacturers in the domestic and international flow of films, performance can be constantly upgraded, there is a big future development of restricted Godson in the MIPS companies.

(2) the structure of purchased license MIPS little cost, the cost of only a small proportion of total R & D costs, or even much lower than the calculation of the costs for the purchase of EDA tools.

(3) branded products in the Godson "MIPS-compatible" label is very easy to get formal recognition of large companies. Cooperation with many manufacturers and Godson Godson was mainly due to the benefits of a MIPS-compatible, STMicroelectronics is one of them. Recently, many multinational corporations began to cooperate with the Godson is also compatible with MIPS as we take the route.

(4) is compatible with MIPS can greatly improve the Godsons industrial environment. Recently, the spiritual leader of the open source community, known RichardStallman on several occasions called for strong support of the open source community Godson-based computer software development, which support the MIPS architecture and the Godson has a close relationship. MIPS architecture as an open architecture for university and graduate teaching computer architecture, the support of the international academic community.

4. Correct understanding of innovation strategies

For the purpose of self-control, the current licensing model is completely controllable mode, mainly to use the "MIPS-compatible" trademark and access to MIPSs services. Godson of all R & D are independent, in the core technology is not controlled by others. The current CPU market is highly monopolized, the threshold is high, the premise in a controlled, Godson need to unite forces.

Very grateful to the calculation of the Godson CPU community concern. As authorized by the community on the structure of meaning is not very clear, resulting in some misunderstanding is understandable. But individual media published an article that the move marks the proprietary CPU core strategy fails, this is a misguided strategy of independent innovation. Compensation for the use of intellectual property licensing and chip design is nothing new, Intel and IBM and other large companies have a year to buy a lot of other companies IP. In a fair and consistent with international practice under the premise of the necessary and reasonable to buy intellectual property and services are part of the strategy of independent innovation one. Advocating all starting from scratch, to a reasonable intellectual property transactions as non-independent innovation to criticize, not conducive to the formation of a real environment for independent innovation.

Godson is like the early Red Army, as part of capacity already has made one or two bases, the pursuit of "pure but pure Bolshevik," the leftist ideology and lay down their weapons and surrender of the Right thought is harmful, adhere to the independent innovation, and the premise in a controlled establishment of a broad united front and unite our forces to win the right way.
