Control of execution of programs in computer using internal events in the processor running real-time preemptive multitasking

摘要

The control procedure pre-loads (302) one or more counters with a first value, and decrements the counter (303) with each occurrence of a predetermined event internal to the processor. The value of each count is compared (304) with a second predetermined value, and when one of the counters attains this second value the program execution is modified (305).
