Run-time middleware to support real-time system scenarios

Systems on Chip (SOC) are powerful multiprocessor systems capable of running multiple independent applications, often with both real-time and non-real-time requirements. Scenarios exist at two levels: first, combinations of independent applications, and second, different states of a single application. Scenarios are dynamic since applications can be started and stopped independently, and a single application's behaviour can depend on its inputs, on different stages in processing, and so on. In this paper we describe how the CompSOC platform offers system integrators and application writers the capability to implement multiple scenarios.
