【摘要】 UNIX实时化是当前UNIX研究中的热点之一,而实时系统的主要量化指标,则是衡量系统适合哪种应用环境的重要尺度。本文着重介绍了HT—RTU工程实践中,对UNIX系统实时化改造前后的主要实时性能指标进行测量的方法,提供了几个性能测量的程序实例,并提出了可能的改进方案。更多还原

【Abstract】 Real-time UNIX is one of the hottest research topics in UNIX and themost important atandard to evaluate the performance of a real time system is its mainnumeric features. In this paper, the methods to test major features before and after modifi-cation to UNIX, by means of experience obtained in HT-RTU engineering, are discussed.Several examples are given and the methods to refine the system are proposed.更多还原
