Scheduling Conditional Task Graphs
The increasing levels of system integration in Multi-Processor System-on-Chips (MPSoCs) emphasize the need for new design flows for efficient mapping of multi-task applications onto hardware platforms. Even though data-flow graphs are often used for pure data-streaming, many realistic applications can only be specified as conditional task graphs (CTG). The problem of allocating and scheduling conditional task graphs on processors in a distributed real-time system is NP-hard. The first contribution of this paper is a complete stochastic allocation and scheduling framework, where an MPSoC virtual platform is used to accurately derive input rs, validate abstract models of system components and assess constraint satisfaction and objective function optimization. The optimizer implements an efficient and exact approach to allocation and scheduling based on problem decomposition. The original contributions of the approach appear both in the allocation and in the scheduling part of the op...
