7. Shenwei: Protect key areas with self-developed instruction sets

Sunway takes "independent innovation" and "safety and controllability" as its research and development priorities. Since its establishment, it has successively launched a series of products based on Sunway processors that are controllable, reliable and have independent intellectual property rights.

It started with the Alpha instruction set and developed the SW64 instruction set to build a basic ecosystem. In terms of instruction set architecture, Sunway's CPU belongs to the Alpha instruction set camp, and the technology comes from Alpha21164 of the American DEC company. After the Alpha architecture was resold and acquired, the instruction set and microstructure are no longer updated, and most of the technology patents have expired or are about to expire. Shenwei is currently the only remaining fruit in the Alpha camp and has the autonomy to expand its instructions and development routes independently. Based on Alpha21164, Sunway has developed its own extended instructions, Sunway Smart compiler and Sunway Ruisi operating system based on Linux. Then Shenwei launched a 100% self-developed order, and all functions were implemented independently. During the development process of the second-generation Sunway processor, it no longer refers to and is compatible with ALPHA-related instruction systems. According to application needs, the instruction system is independently designed and implemented. At the same time, Sunway's independent basic software ecosystem is built based on this.

SW64 is completely autonomous, significantly reducing technology and IP dependence. The Software and Integrated Circuit Promotion Center (CSIP) of the Ministry of Industry and Information Technology, an authoritative organization for intellectual property evaluation, concluded that the Sunway instruction system is: "The Sunway instruction system is a type of instruction system that is similar to previous common instruction systems (ALPHA, MIPS, ARM, X86 , POWER and other instruction sets) different independent instruction systems." Sunway architecture is different from the imported CPU architecture. It is a completely independent architecture, with no restrictions on intellectual property rights and independent research and development capabilities. Shenwei can develop independently without the risk of supply cuts, sanctions or suspension of authorization, and can provide long-term, controllable supply chain and technical support for key areas. Nowadays, domestic systems are basically connected to the SW64 instruction set, such as Kirin operating system, Xin operating system and Euler operating system.

Sunway is a domestically designed chip with a completely independent processor architecture. As the only domestically designed and fully independent processor architecture at present, Sunway has truly realized a domestic processor that is safe and controllable throughout the entire process. Sunway processors feature high computing performance, high integration, high memory access bandwidth, and high I/O performance. Sunway chips cover high-performance, server, desktop and embedded CPUs as well as supporting peripheral IO bridge chips, forming a series of "large, medium and small" and multiple varieties of domestically produced independent chips.

Sunway 26010 processor solves various challenges brought by 260 cores constituting SoC chips, and has a die area close to the process limit. The entire processor supports out-of-order execution, with a frequency of 1.45GHz, and consists of 4 MPE (Management Processing Element) management units, 4 CPE (Computing Processing Element) computing units and 4 MC memory controller units. The CPE unit is composed of an 8x8 array consists of 64 cores, so the total is 260 cores (4x64+4=260).

Sunway 26010 achieved mass production and was used in the "Sunway TaihuLight" supercomputer system deployed in 2016. "Sunway TaihuLight" contains more than 40,000 "Sunway 26010" chips.
