Research on ARINC653 Two level Scheduling Algorithm and Simulation Method Based on Few Partition Splitting

ARINC653 is an important standard for IMA integrated modular avionics systems. In today's rapidly developing world, single core ARINC653 can no longer meet the increasingly diverse tasks and complex systems. Therefore, research on multi-core ARINC653 systems is crucial. This article abstracts the task scheduling of ARINC653 partition system, analyzes the scheduling of ARINC653 multi-core tasks from two levels: inter partition scheduling and intra partition scheduling, and proposes an improved two-level scheduling method. Compared with the traditional ARINC653 scheduling algorithm, this method has fewer partition splitting times. And use AADL modeling language to simulate the system.
