并行或并发操作在计算机系统中具有许多不同的形式。使用基于计算过程中使用的不同流的模型，我们代表了一些不同类型的并行性。流是一系列对象（如数据）或动作（如指令）。每个流都独立于所有其他流，并且流的每个元素都可以由一个或多个对象或动作组成。因此，我们有四种组合来描述最熟悉的并行架构：（1）SISD：单指令，单数据流。这是传统的单处理器[图1（a）]。(2)单指令多数据流。这包括向量处理器以及大规模并行处理器[图1（B）]。(3)MISD：多指令，单数据流。这些是典型的脉动阵列[图1（c）]。(4)MIMD：多指令，多数据流。这包括传统的多处理器以及较新的工作站网络[图1（d）]。
Parallel or concurrent operation has many different forms within a computer system. Using a model based on the different streams used in the computation process, we represent some of the different kinds of parallelism available. A stream is a sequence of objects such as data, or of actions such as instructions. Each stream is independent of all other streams, and each element of a stream can consist of one or more objects or actions. We thus have four combinations that describe most familiar parallel architectures:(1) SISD: single instruction, single data stream. This is the traditional uniprocessor [Figure 1 (a)].(2) SIMD: single instruction, multiple data stream. This includes vector processors as well as massively parallel processors [Figure 1 (b)].(3) MISD: multiple instruction, single data stream. These are typically systolic arrays [Figure 1 (c)].(4) MIMD: multiple instruction, multiple data stream. This includes traditional multiprocessors as well as the newer networks of workstations [Figure 1 (d)].
