In the history of the development of China's semiconductor technology, the name of Academician Shen Xubang shines brightly. As one of the pioneers in the field of embedded computer and chip design in China, Academician Shen's contribution is not only a technological breakthrough, but also a spiritual monument. On August 16, 2024, the great scientist passed away in Xi'an due to illness at the age of 92, leaving behind his indelible contributions to the scientific and technological progress of our country.
1. Academician Shen Xubang's scientific research career
Academician Shen Xubang was born in 1933 and graduated from the Department of Mathematical Mechanics of Peking University in 1957. His scientific research career has run through almost the entire course of the development of computer technology in New China. From the early design of the arrow-borne digital computer to the later research of ultra-large-scale integrated circuits, Academician Shen's work has always been at the forefront of science and technology.
In the 70s of the 20th century, Academician Shen took the lead in carrying out research on domestic integrated circuits and microcomputers, and successfully developed a 16-bit microcomputer with large-scale integrated circuits, achieving a historic breakthrough in China's chip computer. This achievement not only broke the blockade of foreign technology, but also laid the foundation for the independent development of China's computer technology.

2. Technological breakthroughs and industrial impact
Academician Shen's research results, such as NMOS large-scale integrated circuit 16-bit embedded microcomputer, digital signal processing chip, fixed-point and floating-point 32-bit RISC microprocessor chip, etc., have had a profound impact on China's semiconductor industry. The breakthroughs in these technologies have enabled China to gradually move towards independence and controllability in the fields of high-performance computing and aerospace electronics technology.
Specifically, the arrow-borne computer designed by Academician Shen has provided strong computing support for the development of China's aerospace industry. The digital signal processing chip he developed has played an important role in key technical fields such as communications and radar.
3. Academic Achievements and Honors
Academician Shen Xubang's academic achievements are equally remarkable. He has published more than 100 academic papers in journals and conferences at home and abroad, and published seven books such as "Design of Ultra-large-scale Integrated Systems", which has provided valuable knowledge for later generations. In 1997, Academician Shen was elected as an academician of the Chinese Academy of Sciences for his outstanding contributions in the field of computer science. In addition, he has won the National Science and Technology Progress Award 1 time and the third prize 3 times, and was awarded the CCF Lifetime Achievement Award of the China Computer Federation in 2016.
4. Spiritual heritage and future prospects
The death of Academician Shen Xubang is a great loss to China's scientific and technological circles. But his spirit and dedication will forever inspire generations of scientific and technological workers. Academician Shen has repeatedly written and called for the establishment of integrated circuit design centers in universities and research institutes, cultivating relevant talents, and adhering to the road of localization development.
While mourning Academician Shen Xubang, we should inherit and carry forward his scientific spirit and contribute to promoting China's scientific and technological progress and innovation. Academician Shen's life is a life of unremitting pursuit of scientific truth, and his scientific achievements and lofty spirit will always be worthy of our study and remembrance.
5. Write at the end
The death of Academician Shen Xubang reminds us of the importance of independent innovation in science and technology. His scientific research career and outstanding achievements are not only personal glory, but also the embodiment of the country's scientific and technological strength. In remembering Academician Shen Xubang, we should learn from his scientific spirit, continue to work hard in the field of science and technology, and contribute to the realization of the dream of becoming a powerful country in science and technology.
