Abstract :
Modern system design is being increasingly driven by applications such as multimedia and wireless sensing and communications, which all have intrinsic quality of service (QoS) requirements, such as throughput, error-rate, and resolution. One of the most crucial QoS guarantees that the system has to provide is the timing constraints among the interacting media (synchronization) and within each media (latency). We have developed the first framework for systems design with timing QoS guarantees, latency and synchronization. In particular we address how to design system-on-chip with minimal silicon area to meet timing constraints. We propose the two-phase design methodology. In the first phase, we select an architecture which facilitates the needs of synchronous low latency applications well. In the second phase, for a given processor configuration, we use our new scheduler in such a way that storage requirements are minimized. We have developed scheduling algorithms that solve the problem optimally for a-priori specified applications. The algorithms have been implemented and their effectiveness demonstrated on a set of simulated MPEG streams from popular movies
