contentions-conscious dynamic but deterministic scheduling of computational and communication tasks
Real Time Operating Systems (RTOS) for Multiprocessor System-on-Chip (MPSoC) are not well tackling with the scheduling of communication load between the tasks running on different processors. Traditionally communications and computations are considered separately leading to a great complexity in the analysis of the system behavior. We have explicitly scheduled the Inter-Processor Communication (IPC) on the shared medium considering all the parameters affecting its cost i.e. link contention, node contention and synchronization overhead. We have proposed a dynamic but deterministic communication model and have embedded it with the scheduling of the tasks on processors (RTOS kernel services) to get the deterministic behavior of the application.
