要約(英語): In recent year, in order to pursue high functionality of the embedded systems, the function has been increasing and mechanism for concurrent executing functions has been required. System using a real-time operating system are building a concurrent processing using tasks, and high urgency processing and input/output processing are building using the interrupt processing. In this case, there is a possibility that the interrupt processing of low priority to inhibit the interrupt processing of high-priority. Therefore, we proposed an interrupt scheduler REMON(Real-Time Embedded Monitor), and we improved the real-time property of exclusive control of critical section between ISR when using multiple interrupts. REMON is implemented completely in software, but number of resources increases, there is a problem in the state trandition and search sequential processing load is increased. This paper describe the results of performance evaluation and proposal of HW(HardWare)-REMON. It is implementing in hardware scheduler to solve the above problems. By this function, when we have exclusive control to multiple interrupts, we were able to executed the switching of the ISR in two cycles.
