PURPOSE:To simplify the hardware, by providing the address production address register AR reading out the control program from the read only storage ROS, address advance circuit HC and instruction pushup control circuit and the like. CONSTITUTION:The communication control processor 1 consists of the operation program (PR), MS2 storing the control PR and others, read only ROS3 storing the control PR, ROS control circuit 4 transferring the content of ROS3 to MS2 and storing it, and instruction pushup circuit 8 which executes the control PR of MS2, and instruction pushup circuit 8 which executes the control PR of MS2, transfers and stores the operation PR to MS2 from the computer 1a, and executes and controls the operation PR. The circuit 8 consists of the AR storing the address of MS2, ROS3, HC advancing AR, instruction pushup control circuit 5 which sets the address to AR and advances it, and controls write-in/readout of MS2, pushup buffer storing the content of readout of MS2, and processing section 7 judging the content of instruction of operation and control PR and controlling the circuits 4 and 5. |
