| Abstract(in English) | In recent real-time systems, it is necessary to deal with tasks whose execution time varies depending on the situation. Mixed-criticality (MC) systems are capable of extending the worst-case execution time (WCET) in emergencies and executing tasks of high criticality while meeting the time constraints. In recent years, multiprocessor control has become the mainstream of systems, and research on multiprocessor MC systems has been actively conducted. MC-Fluid is a system that applies the optimal multiprocessor scheduling, Fluid Scheduling, to MC systems. Although Fluid scheduling requires constant thread execution speed, MC-Fluid cannot be implemented in a real system because it is not feasible on general processors. However, the IPC (Instruction Per Clock cycle) control mechanism implemented in the RMTP (Responsive MultiThreaded Processor) can control the execution speed of each thread of the SMT (Simultaneous MultiThreading) processor, Fluid scheduling can be realized. In this study, we combined Fluid scheduling using IPC control mechanism and MC-Fluid, and realized an MC system that can realize Fluid scheduling on RMTP. |
