METHOD FOR MONITORING RUNNING TIME OF OS TASK FRAMEWORK AND APPARATUS THEREOF

摘要

PURPOSE: An execution time monitoring method of an OS task and a system thereof are provided to accurately calculate execution time of the task in an RTOS(Real-Time OS) program development process without using periodic interrupt. CONSTITUTION: If an OS(Operating System) task is in a ready state, an initializing unit(110) initializes execution time of the task. If there is an event, a task execution time calculating unit(120) counts, calculates, and stores execution time of the task. A controlling unit(130) executes an exception processing routine.
