The new generation of domestic CPU Loongson 3A6000 independently developed by my country is released

The CPU is the core of computer computing and control, directing the operation of various components just like the human “brain”. On November 28, the Loongson 3A6000, a new generation of general-purpose CPU independently developed by my country, was officially released in Beijing. Shi Huikang, deputy director of the Electronic Information Department of the Ministry of Industry and Information Technology, said that this marks that domestic CPUs have reached a new height in terms of independent controllability and product performance, and also proves that my country has the ability to produce first-class products based on self-developed CPU architecture.

The Loongson 3A6000 released this time adopts the instruction system and architecture independently designed by my country and does not need to rely on foreign authorized technology. It is a new generation of general-purpose processor independently developed by my country and independently controllable. It can run a variety of cross-platform applications and meet the needs of many types of applications. Large and complex desktop application scenarios.

Generally speaking, there are two main ways to improve CPU performance, one is to increase the main frequency, and the other is to optimize the core design. The performance improvement of Loongson 3A6000 is mainly achieved through design optimization. Its main frequency reaches 2.5GHz, integrates 4 newly developed high-performance LA664 processor cores, supports simultaneous multi-threading technology, and has a total of 8 logical cores in the whole chip. Compared with the previous generation Loongson 3A5000, the performance of single-threaded general-purpose processors has been improved by 60%, and the performance of multi-process general-purpose processors has been improved by 100%.

Test results from the China Electronics Technology Standardization Institute’s Saixi Laboratory show that the overall performance of the Loongson 3A6000 processor is equivalent to Intel’s 10th generation Core quad-core processor launched in 2020.

The degree of autonomy and controllability of Loongson 3A6000 is second to none among domestic general-purpose CPUs. Focusing on the completely self-designed command system Dragon architecture, Loongson not only launched a self-developed CPU core, but also integrated GPU core, encryption and decryption IP, high-speed transmission interface IP, storage interface IP, audio and video interface IP, UART and other interfaces IP, as well as hard-core IP such as register files of various specifications, are also self-developed.

“The fundamental way out for my country’s information industry is to build an independent ecological system independent of the X86 and ARM systems.” said Hu Weiwu, chairman of Loongson Zhongke and a researcher at the Institute of Computing Technology of the Chinese Academy of Sciences. After years of accumulation, Loongson Zhongke has consolidated the foundation of the independent information industry in terms of chip research and development based on independent IP and software ecology based on independent command systems.

The Dragon architecture, which has the characteristics of complete independence, advanced technology, and ecological compatibility, has now built a Linux basic software system in parallel with It supports operating systems such as La, Dragon Lizard, and open source Hongmeng, as well as basic applications such as WPS, WeChat, QQ, DingTalk, and Tencent Conference.
