Embedded multimedia systems often run multiple time-constrained applications simultaneously. These systems use multiprocessor systems-on-chip of which it must be guaranteed that enough resources are available for each application to meet its throughput constraints. This requires a task binding and scheduling mechanism that provides timing guarantees for each application independent of other applications while taking into account the available processor space, memory and communication bandwidth. Synchronous DataFlow Graphs (SDFGs) are used to model time-constrained multimedia applications. They allow modeling of cyclic, multi-rate dependencies between tasks.
