PURPOSE:To improve the processing efficiency of the whole system by forming a reloading processing task and requesting processing which is to be essentially executed by an operating system(OS) based on its own duty to the task. CONSTITUTION:At the time of detecting abnormality in a program module 5A e.g., a module validity checking means 6 informs the detection to the OS2. The OS2 stops the processing of a task 3a and starts a task 3x. The task 3x senses the means 6, acknowledges that the module detected at its abnormality is the module 5A and reloads a valid module 5A from an external storage device 7 to a main memory device 4 based on a reloading means 8. During the period, the OS2 switches the processing of the tasks 3b, 3c, 3x to execute the switched task. After ending the reloading of the valid module 5A, the task 3x informs the end to the OS2 and the OS2 restarts the processing of the task 3a. |
