Hardware-software co-synthesis of fault-tolerant real-time distributed embedded systems

Distributed systems are becoming a popular way of implementing many embedded computing applications, automotive control being a common and important example. Such embedded systems typically have soft or hard performance constraints. The increasing complexity of these systems makes them vulnerable to failures and their use in many safety-critical applications makes fault tolerance an important requirement. This paper is the rst to address the problem of automatic hardware-software co-synthesis of fault-tolerant embedded distributed real-time systems in a generalized scenario. We present an algorithm which takes as input the specication of the data- ow information in the form of a task graph, the performance constraints, the fault tolerance requirements and the available hardware resources in the form of processor, ASIC and link libraries. Our algorithm then synthesizes the required hardware as a distributed system in terms of the component processors, ASICs and interconnection links....
