Task Management Apparatus and Method used Task Scheduling Table of Real-time Operating System

摘要

PURPOSE: A task management device using an array-type task scheduling table of a real-time operating system and a management method thereof are provided to comprise the task scheduling table that the operating system refers for a context switch as an array, thereby improving real-time performance of the operating system. CONSTITUTION: A memory(20) stores tasks by comprising a task scheduling table(21) which is fixed by using arrays in a constant area. When one task is executed in an operating system, a microprocessor(10) stores a current task in the task scheduling table by determining generation of a context switch and executes a next task by reading the same. A specification of each task is assigned to the task scheduling table.
