Abstract: PURPOSE:To enable a task whose access to a shared resource is interrupted to access the common resource without waiting the generation of a dispatching request from another task by interrupting a CPU by a write access from the task concerned to the shared resource. CONSTITUTION:When a CPU 1 outputs an operation request to the shared resource 5 in a system including a real time OS for accessing the shared resource 5 by a program request, the OS executes operation so that the competition of the shared resource 5 is not generated. Namely, when a CPU 8 outputs an operation request to the same resource 5, the OS makes a task in operating in the CPU 8 wait and executes dispatching to execute another task. An interruption generating circuit controller 4 and an interruption generating circuit 7 are driven by a memory write access signal to the resource 5 and an interruption request signal 9 is generated to the CPU 8. Thereby, the CPU 8 can separate the task from a shared resource operation queue and execute dispatching.
