關於SISD

SISD computersA SISD computer consists of a single processing unit receiving a single instruction stream that operates on a single stream of data. At each step, the control unit emits one instruction that operates on a datum obtained from the memory unit. Almost all computers in use today adhere to this model invented by John von Neumann in the last 1940s. An algorithm that runs on a SISD computer is said sequential (or serial), as it does not contain any parallelism.
