On November 28, 2023 Loongson product launch and user Conference was launched at the National Convention Center.

On the same day, the new generation of general purpose processor Loongson 3A6000 and printer master chip Loongson 2P0500 were released on the site, and the core IP of Loongson processor and the authorization plan of Loongson independent instruction system architecture were announced.

In his speech at the conference, Long Kai, deputy director of the Information Development Bureau of the Central Network Information Administration, congratulated Loongson on its achievements. In recent years, Loongson has continuously promoted core technology breakthroughs, the performance of domestic chips has continued to improve, and the industrial ecological construction has made great progress. Shi Huikang, deputy director of the Electronic Information Department of the Ministry of Industry and Information Technology, said in his speech at the conference that the launch of the Loongson 3A6000 processor shows that the domestic CPU has reached a new height in the degree of autonomy and product performance, and also proves that the domestic has the ability to make first-class products on the self-developed CPU architecture. Gu Jinxu, a member of the Party group and deputy director of the Beijing Municipal Bureau of Economy and Information Technology, said that Longson, as a representative of technological innovation enterprises in Beijing, has fully made efforts to accelerate the major leap forward in independent information technology and provide solid support for scientific and technological self-reliance.

The Loongson 3A6000 processor was officially released at the conference. The Loongson 3A6000 processor is fully self-designed and has excellent performance, representing the latest milestone in the field of autonomous desktop CPU design in China.

3A6000 General purpose CPU chip

LoongArch is the first product of the fourth generation microarchitecture of Loongarch, with a dominant frequency of 2.5GHz. It integrates 4 high-performance LA664 processor cores, supports simultaneous multi-threading technology (SMT2), and has a total of 8 logic cores. Integrated secure and trusted module provides secure startup solutions and application support for state secrets (SM2, SM3, SM4, etc.).

According to the test results of the Ceci Laboratory of the China Institute of Electronic Technology Standardization, at the frequency of 2.5GHz, the single thread fixed/floating point value of the SPEC CPU 2006 base reaches 43.1/54.6 points, and the multi-process fixed/floating point value reaches 155/140 points, respectively. SPEC CPU 2017 base single-thread (rate1) fixed/floating point score of 5.05/7.78 points, single-process multi-thread (speed) fixed/floating point score of 6.66/18.1 points, multi-process (rate8) fixed/floating point score of 21.3/21.0 points. Stream bandwidth measured over 42GB/s; Unixbench test scores over 7400 points. Based on the relevant test results, the overall performance of the Loongson 3A6000 processor is comparable to Intel’s 10th-generation core quad-core processor to be launched in 2020.

The Loongson 3A6000 is compatible with Dragon architecture processor software such as the Loongson 3A5000. Tongxin, Kirin and other operating system companies have fully supported the new features of Loongson 3A6000 on the basis of continuous compatibility. Loxson 3A6000 improves the support for binary translation of soft and hard collaboration, which can improve the efficiency of binary translation, run more kinds of cross-platform applications, and meet various large-scale and complex desktop application scenarios.

2P0500 printer main control chip

Loongson 2P0500 is a master SOC chip for single/multi-function printers. The chip adopts heterogeneous size core structure, integrates DDR3 memory, GMAC, OTG and other functional modules, with print data reception, analysis and processing, print engine control, scan timing control, data scanning, image processing, motor control and other functions, a single chip can meet the needs of printing, scanning, copying and other typical applications. Based on Longson 2P0500, Longson launched a variety of solutions such as printers, scanners, copiers, and cooperated with a number of domestic mainstream printer manufacturers to complete a variety of applications such as printing, scanning, copying.

Hu Weiwu, chairman of Longson Zhongke, said that building a new information technology system and industrial ecology independent of X86 and ARM is an important part of realizing the “Chinese Dream” of the great rejuvenation of the Chinese nation. Standing at a new historical starting point, Longxin Zhongke will always adhere to the fundamental purpose of doing Longxin for the people, adhere to the work style of self-reliance and hard struggle, adhere to the thinking and method of seeking truth from facts, bravely forge ahead on the new journey of building the information technology system and industrial ecology, and strive to achieve self-reliance in China’s information industry!
