Series of computer microprocessors developed by Jiāngnán Computing Lab
Sunway , or ShenWei , (Chinese : 申威 ), is a series of computer microprocessors , developed by Jiangnan Computing Lab (江南计算技术研究所 ) in Wuxi , China .[ 1] It uses a reduced instruction set computer (RISC) architecture, but details are still sparse.
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 .[ 2] [better source needed ] The SW-3 is thought especially to be based on the Alpha 21164 .[ 3]
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;[ 4] [ 5] although precise details of the instruction set are unknown.
