Abstract :
We propose a new task scheduling algorithm for timed-functional simulation of concurrent software tasks. It attains efficiency by reducing the frequency of context-switching between concurrent tasks. It also provides a high-degree of portability in the sense that it only needs the underlying system to support a very small number of primitives. We provide a concrete implementation built on top of the SystemC scheduler and show some results of preliminary evaluation
