A Software-Reuse Approach to Build Monitor Programs for Soft Real-Time Applications

Thispaper describes the implementation of an integration frameworkto build real-time monitor programs based on software reuse.A custom-made real-time monitor program can be built very quicklyby integrating existing monitor programs on commercial operatingsystems, where limited real-time system support is provided.We address issues related to software control, output re-processing,data age, and interactivities of program executions. The feasibilityof this framework is demonstrated by the construction of an integrationenvironment and a monitor program built by the environment forsoft real-time applications in the Microsoft Windows operatingsystems. We also measure the incurred system overheads of thisapproach.
