Dynamically reconfigurable embedded systems offer potential for higher performance as well as adaptability to changing system requirements at low cost. Such systems employ run-time reconfigurable hardware components such as field programmable gate arrays (FPGAs) and complex programmable logic devices (CPLDs). In this paper, we address the problem of hardware/ software co-synthesis of dynamically reconfigurable embedded systems. Our co-synthesis system, CRUSADE, takes as an input embedded system specifications in terms periodic acyclic task graphs with rate constraints and generates dynamically reconfigurable heterogeneous distributed hardware and software architecture meeting real-time constraints while minimizing the system hardware cost. We identify the group of tasks for dynamic reconfiguration of programmable devices and synthesize efficient programming interface for reconfiguring reprogrammable devices. Realtime systems require that the execution time for tasks mapped to reprogra...
