A Multi-core Based Real-time Scheduler Supporting Periodic and Sporadic Threads and Processes

Abstract

This paper proposes, implements, and verifies a multicore real-time scheduler (MCRT scheduler) for periodic and sporadic threads and processes, and non-real-time processes where periodic and sporadic (or eventdriven) processes are processed according to real-time characteristics such as limited periods and deadlines. Using the Xenomai and Linux operating systems, the proposed MCRT scheduler was implemented and verified through various test cases designed for multicore operations. The proposed MCRT scheduler generates scheduling tables for periodic and sporadic threads and processes, based on which they are executed during the basic period. The MCRT scheduler was verified using several examples.

Keywords Multicore, periodic, process, real-time scheduler, sporadic, thread.
