Memory medium scheduler, realtime system and scheduling method

摘要

PROBLEM TO BE SOLVED: To provide a storage medium scheduler, a real time system and a scheduling method which normally process stream data that have temporal constraint and are severely managed and which also normally process non- stream data. SOLUTION: Request execution orders are switched in real time so as to optimize processing by having two types of queues to a request provided with a parameter, processing that plans a request execution order according to the parameter and processing that scans the queues and executes an optimum request.
