For task assignment and scheduling problems of multiprocessor real-time control systems, a new performance index called the control latency, is proposed. In order to ensure smooth operation and good performance of real-rime control systems, one must analyse the problem of combined task assignment and scheduling during the conceptual system design stage. The proposed performance index, the control latency, is defined as a weighted sum of feedback, command and monitoring latencies. Given a set of tasks for a specific control application, each task execution time and intra-/interprocessor communication latencies, an algorithm for combined task assignment and scheduling can be solved by minimizing this performance index, thereby providing the minimum time delay and best performance.
