Loongson-1, China's First General-purpose High-performance Microprocessor chip with Independent Intellectual Property Rights

2024-10-21

On August 10, 2002, China's first general-purpose CPU, Loongson-1, was successfully taped out (the process of checking and testing whether the chip satisfies the design performance and functionality), ending the history of China's computer industry being "no-chip" and breaking through the situation of "chip shortage" in China's computer industry.

 

Hu Weiwu (1968-), a researcher of the Institute of Computing Technology of the Chinese Academy of Sciences and the leader of the "Loongson-1" development team, led the researchers to successfully develop the first general-purpose high-performance microprocessor chip with independent intellectual property rights in China -- " Loongson-1". It was born on August 10, 2002, it adopts the independent LoongISA instruction system and is compatible with MIPS instructions. Its functionality is equivalent to that of the Pentium II, which is a milestone in the history of computer development in China. It is a representative work of developing high-performance general-purpose CPUs with independent intellectual property rights in China. From that moment on, the Chinese people ended the history of making computers only with foreigners' CPUs, and turned a new page in China's computer industry.

 

Hu Weiwu, Chairman of Loongson Technology and Chief Engineer of the Institute of Computing Technology, Chinese Academy of Sciences, said that the development process of Loongson is full of obstacles and difficulties. In addition to the need to improve the R&D process, the fundamental reason is that the team insists on developing its own core modules, and the challenge is the most difficult problem.

 

In the "Dialogue" program of CCTV Finance Channel, Hu Weiwu elaborates how the first domestically produced CPU was born. The people who is interested on this can click on the video below to watch and learn about the birth history of "Loongson-1".
