Abstract
A control apparatus for an input-output device includes a hardware part and a software part, in which a controller in the hardware part carries out a control operation in accordance with a signal from the input-output device, outputs a result of the control operation to a process, and has a timer unit to be excited at a constant period; and the software part has an information process part, a control process part, and an interrupt control unit to switch over the information process part and control process part one another, in which the interrupt control unit suspends an execution of the information process part to execute the control process part in priority and resume the information process part by switching over to the information process part from the control process part, when the execution of the control process part is terminated.
