浅析处理器流水线冒险原因和解决方案

Analysis of processor pipeline risk reasons and solutions

处理器流水线技术是一种广泛应用于CPU的关键技术并行处理技术。它是指在程序执行过程中一条指令拆分成几个步骤由不同的处理单元组成的流水线分别执行,在时间上并行处理。从而达到提高运行效率的目的。而流水线过程的执行可能受到指令和数据间的约束关系的制约,从而使程序执行中断。本文将对这一现象的原因及解决办法展开描述。

Processor pipeline technology is a key technology which is widely used in CPU parallel processing.It refers to the execution of a instruction in the process of a program into several steps by different processing units of pipeline execution,in time parallel processing.Thus,the purpose of improving the operation efficiency is achieved.The execution of pipeline process may be restricted by the constraint relationship between instruction and data,which can interrupt the execution of the program.This paper will describe the causes and solutions of this phenomenon.
