100% independent Loongson architecture! Beihang University successfully taped out two CPUs

July 15 news, recently, the School of Computer Science and Technology of Beihang University successfully taped out the Lain and EULA processors based on LoongArch dragon architecture instruction set of Loongson Zhongke.

Both have a complete SoC structure and rich peripheral support. They can not only run the MOS teaching operating system designed independently by the college, but also support Linux 5.19, as well as complex multimedia audio and video application software.

Among them, the Lain processor focuses on verifying modern CPU mainstream microarchitecture technologies such as multi-issue, out-of-order, and multi-core, while the EULA processor focuses on verifying the chip agile development environment and its full-process design support.

This achievement comes from the "Beihang-Loongson Hundred Cores Plan", which was officially launched in 2020. It is goal-oriented for undergraduate development and tape-out, led by the School of Computer Science, and jointly with the School of Integrated Circuits and the School of Software, to jointly explore and practice cross-disciplinary talent training models across colleges, disciplines, and majors, and cultivate scarce and outstanding innovative talents for the country with full-process capabilities from CPU, operating system, compiler to chip implementation.

The design team of Lain and EULA processors completed the hardware front-end and back-end design from CPU core and SoC chip to software development tasks such as operating system, compiler and even application program, running through the entire technology stack of processor chip design, demonstrating a very high degree of completion and realizing the full stack connection of domestic independent and controllable processor chip design capabilities.

The "Hundred Cores Project" is an industry-university-research integration project launched by Loongson Technology. It plans to select 100 universities across the country within 5-10 years to jointly build 100 chip joint laboratories through a school-enterprise cooperation model.

Based on the IP provided free of charge by the Loongson University Program, the joint laboratory will work with a third party to jointly develop a practical independent chip, and form industrial applications, forming an ecosystem based on Loongson's independent chip IP, and promoting the integration of industry and education, and science and education.

In 2023, the first chip of the Hundred Cores Project, BX100E-HHU, was officially released. It was designed and developed by Hohai University based on the Dragon architecture instruction set. It has passed comprehensive verification and will be used in practical work in embedded, Internet of Things, and intelligent industrial control fields.

In 2024, the first 32-bit MCU chip "Suxin No. 1" for domestic higher vocational education jointly developed by Loongson Technology and Jiangsu Information Vocational and Technical College was successfully taped out, and has broad application prospects in automotive, industrial control and consumer fields.
