TASK SCHEDULING PROCESSING SYSTEM AND METHOD FOR EMBEDDED REAL-TIME OPERATING SYSTEM

WIPO Patent Application WO/2021/139560

A1

A task scheduling processing system and method for embedded real-time operating system, the system comprising a processor, and a timer, an interrupt controller, a scheduler and an SVC switching module that are provided in the processor. The scheduler comprises a priority scheduler and a time slice polling scheduler. The present invention using a scheduling means that is on the basis of priority preemption to always allocate CPU usage rights to the currently ready task having the highest priority, and schedules the tasks having the same priority according to a first in first out means; at the same time, a time slice polling scheduling method is used as a supplement to the priority preemption scheduling means, and the problem in which real-time performance of a processor system is low because multiple ready thread tasks having the same priority are sharing the processor can be coordinated and the problem of processing multiple ready thread tasks having high priority is ameliorated.
