Sunway, or ShenWei, (), is a series of computer microprocessors, developed by Jiangnan Computing Lab () in Wuxi, China. It uses a reduced instruction set computer (RISC) architecture, but details are still sparse.
History The Sunway series microprocessors were developed mainly for the use of the military of the People's Republic of China. It is expressed on online forums that the original microarchitecture is believed to be inspired by the DEC Alpha. The SW-3 is thought especially to be based on the Alpha 21164.
Jack Dongarra states about the follow-on SW26010, the "ShenWei-64 Instruction Set (this is NOT related to the DEC Alpha instruction set)", and doesn't say it's a new instruction set from the three prior generations he names; although precise details of the instruction set are unknown.
