Research And Realization Of A Software Logic Analyzer

Because real_time software is applied to special fields, its function and reliability are very important. Real_time software testing is very strict. Many bugs are not be find until software runs in real work environment. We should focus on timing test when testing real_time software. The software profiler is a test tool to meet these demands. When software profiler is testing program, the program is not broken off as if it is running in real work environment. The software profiler can find software bugs though analyzing timing.DeltaCORE2.0 is a real_time operating systems of the Coretek System Co.. The company plans to provide a set of development and test tools for users of DeltaCORE2.0. GammaProfiler is a software profiler based on DeltaCORE2.0.In the paper, firstly, the author analyses a typical software profiler, interpret the concept of event deeply, event abstract and method of event abstract. Then, the author designed and implemented GammaProfiler program. In the process, I elaborated the design principle, discussed disturbing problem in target program, used index table to quickly search for data in a large file, added unreal event information to log file to display task state on monitor. Finally, two programs demonstrate that GammaProfiler attain to design goal and the design scheme is high efficiency and open. The work is a basis for the next work.
