TASKS SCHEDULING METHOD FOR REALTIME OPERATING SYSTEM

摘要

PURPOSE: A task scheduling method of a real time operating system is provided to omit additional memory space for managing priority by sequentially placing tasks in a queue according to the priority. CONSTITUTION: Execution priority for a new task of an execution preparation state is confirmed (S210). The execution priority for each task in a prepared queue is sequentially investigated. A task having lower priority than the execution priority is derived by the investigation (S220). The new task is added to the front of the derived task (S230).
