METHOD AND DEVICE FOR PREDICTING AND DISPLAYING TASK SCHEDULING

摘要

PROBLEM TO BE SOLVED: To provide debug environment in which task transition is easily and intuitively grasped by predicting and displaying a task transition state when a multi-task program operated on an OS is debugged. SOLUTION: A scheduling information acquiring part 160 in a debugger 130 acquires the internal data of the OS from a debug control part 120 in a program 100, stores the data into a storage part 161 and creates a Ready Queue for pseudo-scheduling from a task status in an acquired TCB. A control block control part 153 updates a relevant control block if necessary. A pseudo- scheduling executing part 170 rearranges tasks in the order of the highest priority in the Ready Queue when tasks at Ready states exist, and a display part 180 acquires and displays information of the task to be transited next.
