Abstract

PURPOSE:To more quickly execute a task of an emergency request by providing a control means for interpreting the contents of an executing state holding means, and subsequently, executing a selection processing of a task to which a control is to be shifted. CONSTITUTION:For instance, a status register 10 is provided as an executing state holding means, and an executing state of a processing to be executed on a central processor 1 is held. A control means checks the executing state which is held in the executing state holding means, and when it is interpreted that its contents are an OS processing state which is requested and executed in a task executing state or in the course of executing a task, a task switching processing which is determined in advance as a specific processing is executed, and a task which is requested urgently is selected and executed. Accordingly, even in the course of OS processing, when an emergency request is generated, a task switch processing can be started, and the task which is requested urgently can be executed more quickly.
