单指令流单数据流(Single Instruction Stream Single Data Stream):一种计算机架构,指在同一时间内,计算机只能执行一个指令并处理一个数据流。这种架构在传统的串行计算机中较为常见。
例句
In an SISD architecture there is a single instruction cycle; operands are fetched serially into a single processing unit before execution.
在单指令流单数据流结构中,有单一的指令周期,在执行前,单个处理机按序取操作数。
Because of this similarity, some methods from high-speed pipeline SISD computers can be extended to array processors or vector computers, and vice-versa.
