摘要 通用处理器以其优异的性能已经越来越广泛地应用到实时控制系统中,但其所采用的体系结构会引起指令执行时间的不确定性,导致基于它的实时系统存在调度抖动问题.调度抖动是实时控制系统的重要性能指标之一,本文讨论了抖动测试和分析技术,并介绍了减少抖动的补偿技术. General-purpose microprocessors are increasingly being used for real-time control systems due to their excellent performance, but the uncertainty of instructions execution times introduced by their adopting architeeture causes the problem of scheduling jitter that exists in real-time systems based on them. Scheduling jitter is one of the most important performance criterions of real-time control systems. This paper discussed the techniques of jitter measurement and analysis, and presented the compensation techniques to reduce jitter.
