METHOD AND SYSTEM FOR PERIODICALLY PERFORMING REAL-TIME OPERATION INCLUDING MULTIPLE SEQUENTIAL TASKS

摘要

PURPOSE: A method and a system for periodically performing a real-time operation including multiple sequential tasks are provided to effectively perform the real-time operation including a combination of the multiple sequential tasks by using multiple processors. CONSTITUTION: The system includes multiple VPUs(Versatile Processing Unit)(12), a device for dividing the sequential task into the first task group and the second task group executed next the first task group, and the device for performing a scheduling operation to periodically assign the first and the second task group at least one VPU. The system includes a main memory(14) shared by the VPUs, the device for reserving a buffer to the main memory when execution of the first task is started, and the device for releasing the buffer when the execution of the second task is completed.
