Mixed criticality functions integrated on a single computing platform require special attention to safety and security. ARINC 653 and DO-248 provide guidelines for partitioning software so that functions of differing levels of criticality are isolated from one another. The partitioning environment operating system isolates each partition, and because it is foundational it must be certified to the...
Interrupts are forbidden in ARINC 653 partitioned environments — or so it appears. In this paper we will examine that prohibition and explore a means of using interrupts in a system while maintaining deterministic behavior. We begin with an overview of the benefits and costs of Integrated Modular Avionics (IMA), along with a review of associated standards. Next, we look at interrupt-driven Input/Output...
