PURPOSE:To make the size of processor small and to make it efficient, by making common a control section which is in common state common, through one submonitor section, as one device on the hardware among input and output devices of data. CONSTITUTION:A monitor section MON starts submonitor section SM0 or SM1 through the request of an application section APL. For example, the submonitor section SM0 distinguishes the transmission or reception through it and gives the right of processing operation to a transmission task section SS or reception task section SR. The selected task section executes the pregiven processing to the task section. Similarly, the submonitor section SM1 manages output task OT and input task IT to keyboard KB and display DP. Thus, the interface control can be simplified by common input and output from one device to other processing sections. |
