Multi-core processor partitioned task scheduling algorithm design based on ARINC653

Abstract

The Integrated Modular Avionics (IMA) has become a popular aircraft avionics system, and ARINC653 is a standard interface for IMA architecture of aircraft avionics equipment, and real-time scheduling for ARINC653 partition Operating System (OS) is a key issue. There are lots of scheduling algorithms for ARINC653 partition OS based on a single-core processor. This paper presents a partition scheduling proposal based on parameter configuration and designs a scheduling algorithm based on multi-core Load Proportional Round-Robin (MLPRR). The algorithm calculates the task weight according to the load ratio of the task and completes the scheduling of the task on the multi-core processor to meet the real-time requirements of the multi-core partition OS. Experimental results show that MLPRR is feasible and efficient.
