ABSTRACT:
A task tracing apparatus stores causes and addresses of interruptions, and system call numbers and addresses of system calls issued by an ongoing task. This makes it possible to obtain not only the basic information about switches from one task to another, but also the other related and detailed information as needed. Thus the development of software systems is made easier and more efficient.
