Become attached to scientific research and devote yourself to scientific research Shen Xubang 1933 Shen Xubang, a native of Lantian Village, Huofeng Township, Linli County. Shen Xubang 1953 was admitted to the Department of Mathematics of Wuhan University, and 1956 joined the Party. In the same year, he was transferred to the Department of Mathematical Mechanics of Peking University to study computer science. 1957 graduated and was assigned to the Institute of Computing Technology, Chinese Academy of Sciences.
For decades, he has been engaged in the design and development of aerospace computers and their domestic chips, and has made great contributions. From 65438 to 0965, he designed and developed the first domestic bipolar small-scale integrated circuit space guidance computer and the first domestic PMOS medium-scale integrated circuit space guidance computer, which promoted the rapid development of PMOS integrated circuit technology in China. 1977, the first domestic 16-bit microcomputer for NMOS large-scale integrated circuit aerospace was developed and won the third prize of national scientific and technological progress. The special LSI arithmetic logic unit ALU developed by him won the third prize of 1988 National Defense Science and Technology Progress Award.
Since 1982, 22 doctoral students have been trained and 3 are studying for master's degree. After 1986, 10 doctoral students have been trained and 7 doctoral students are studying. In order to promote the development of domestic chip computers, he wrote five monographs, such as Digital Signal Processing Computer, VLSI Design and RISC and Post-compilation Technology. After the Gulf War, he completed the architecture design of LSRISC microcomputer. 1995 completed the development of a fixed-point 32-bit RISC microprocessor chip and won the third prize of 1997 National Science and Technology Progress Award. 1996 completed the scheme design of LSMPP embedded massively parallel processing computer. 1997 completed the development of MPP processor chip at the peak speed of 320 million fixed-point addition and subtraction operations per second. At present, floating-point RISC microprocessor chip and MPP embedded computer are being developed.
Shen Xubang is critical of comparing Zhongguancun to Silicon Valley in China, but some people think that if Zhongguancun can't be called Silicon Valley in China, then no other place in China can be called Silicon Valley. This longing for some "Silicon Valley" in China makes it understandable that the Silicon Valley miracle will also happen in our country. However, without silicon, there would be no Silicon Valley, and it was silicon that finally created the modern information industry based on chips. Zhongguancun cannot be called the Silicon Valley of China. The reason is that there is no silicon wafer production base in China, not because of environmental conditions and incentive mechanism. Silicon Valley is not vividly painted with a pen, but watered with sweat.
At the beginning of his research, he was engaged in the design of two kinds of digital computers and their small and medium-sized integrated circuits. A new method of multiple integral error correction, two new architectures of missile-borne computer and a new test scheme of missile-borne system are proposed, which have made outstanding contributions to solving the miniaturization problem of missile-borne computer.
Researcher Shen Xubang has been engaged in the design of computer architecture, embedded computers and their chips. Two kinds of embedded computers, a 16-bit dedicated microcomputer, four DSP chips, a fixed-point 32-bit RISC chip and two MPP embedded computer chips, have been completed successively. He has written five books, including VLSI design, totaling more than 2 million words. Currently engaged in RISC and MPP embedded computer research. 1997 was elected as an academician of China Academy of Sciences. Look at the fragment: In the SPMD style of MIMD machine, although the programs stored in each processor are exactly the same, the execution order of instructions in the programs is not necessarily the same, which will lead to different instructions executed in each cycle. For example, in figure 1. 1 1, the execution order of statements, that is, the execution order of instructions, is not necessarily the same with the different conditions in various processors. Different execution order of statements will bring synchronization problems.
The introduction and research of silicon wafer is the bread of high-tech development, and high-tech development cannot be separated from silicon wafer. Therefore, the silicon wafer production base in China should also be built like Silicon Valley in the United States, and become the miracle source of China's scientific and technological development. Semiconductor industry is the foundation of information industry, and knowledge economy is based on information industry. Therefore, if China wants to become a world power, it cannot do without its own Silicon Valley. China has invested tens of billions of dollars to introduce some production lines that will be eliminated in developed countries, so that it only takes China 10 years to complete the road that developed countries used to take for 20 or 30 years, which quickly shortens the gap between China and advanced countries. This introduction is absolutely necessary. However, although the risk of importing and transplanting ready-made things from abroad is small, and it is easy to get immediate results and social recognition, what you create is often risky. "Cats can't teach tigers to climb trees", that is to say, the chip manufacturing technology production line representing the contemporary advanced level cannot be introduced, and others transfer technology only because they have more competitive new technologies in their hands. Therefore, we must deal with the relationship between introduction and self-reliance. In order to change the unfavorable situation that China has always lagged behind advanced countries in wafer manufacturing technology, only by self-reliance and catching up, can we truly occupy a place in the international competition by building China Silicon Valley.
Imitation and innovation The basic feature of knowledge economy is the continuous innovation of knowledge. In order to quickly form an innovative mechanism and atmosphere in China and change the backward situation of wafer technology in China, it is very correct to change from imitation to continuous innovation. Imitation does play a very good role in dealing with small and medium-sized integrated circuits, but now the chip integration is too high, anatomical analysis is becoming more and more difficult, and the road of imitation is impassable. It is believed that imitation is to follow others consciously and voluntarily, never surpass others and never innovate, which is not conducive to cultivating independent and innovative scientific and technological talents. Intel's history shows that they have achieved and maintained their success through continuous innovation of core technologies. As the world's largest semiconductor memory manufacturer, Intel was pushed to the "Valley of Death" by its Japanese counterparts in the early 1980s, and finally had to give up memory chips and boldly innovate and develop microprocessor chips to get out of the predicament. One thing that made me think deeply in particular was the appearance of the Linux operating system named Windows Gravedigger. A Finnish college student who was only 2 1 year old completed a Unix-like operating system on an Intel386 microcomputer in 199 1 year, which was the earliest version of Linux operating system. Such working conditions are also available in China. If copying a compatible operating system product is not restricted, will college students in China create a similar miracle? If you can only copy, it is really impossible. From this point of view, in order to build China Silicon Valley, the whole society should overcome the psychological influence of Confucian tradition and strive to create a good environment and mechanism with innovation as the mainstay.
