Decoupled Inter-And Intra-Application Scheduling for Composable and Robust Embedded MPSoC Platforms
System-on-Chips (SoCs) typically implement complex applications, each consisting of multiple tasks. Several applications share the SoC cores, to reduce cost. Applications have mixed time-criticality, i.e., real-time or not, and are typically developed together with their schedulers, by different parties. Composability, i.e., complete functional and temporal isolation between applications, is a SoC property required to enable fast integration and verification of applications. To achieve composability, an Operating System (OS) allocates processor time in quanta of constant duration.
