摘要
进程间通信技术是实现实时控制软件设计的关键技术,其实时性、可靠性是影响实时控制软件性能的重要指标。论文针对实时控制软件需要在进程间频繁传递小量信息问题,分析了POSIX 1003.1b实时接口库中实时信号的功能特性,设计了一种利用实时信号在进程间传递小量信息的聪明机制,并在实时性方面与其它进程间通信技术进行比较分析。
Interprocess communication is key technique to realize real-time control software design, whose real-time, reliability is the important indicator of performance of real-time measurement and control software. In this paper, according to the problem of a little informa- tion convey in real-time control software frequently, the features of the real-time signal of POSIX 1003. lb real-time interface library is ana lyzed, a smart mechanism of using real-time signal achieves interprocess communication goal is designed and compared with other interprocess communication in real-time aspect.
