Some scheduling experiments with ARTIE

Abstract

In this paper we describe a new Architecture for hard Real-Time Environments (ARTIE). The architecture is essentially an asymmetrical two-processor system. It consists of a task processor for the application programs and the operating system's shell functions, and of a reliable co-processor for the real-time operating system kernel. We have formally derived the specifications for the kernel programs and proved that the programs behave according to the specifications. The practical performance of the system is evaluated by simulating a typical real-time application on a workstation.
