Prototype Real-Time Monitor: Design

November 1987 Technical Report
Roger Van Scoy, Chuck Plinta, Rich D'Ippolito, Kenneth Lee, Michael Rissman

The requirements imposed by flight simulators and good software engineering practice on Ada systems force software engineers to seek new solutions to the problem of monitoring executing software. This report examines some of these requirements and, based on these requirements, defines a subset for implementation as a prototype real-time monitor (RTM).

This report describes the software design used to implement the prototype real-time monitor requirements. The design is presented at three levels: system level, object level, and package architecture level. The report concludes with a discussion of the key implementation obstacles that had to be overcome to develop a working prototype: determining system addresses, communicating with an executing application, accessing application memory, converting data into human-readable form, and distributed CPU architectures.
