This paper is proposed for designing and implementation of control computer system using HD64180 microprocessor. Control computer systems that have event and logging printer device, text displayer, subcomputer by communication, keyboard, analog I/O, digital I/O and pluse I/O control and monitor the device of factory field.
The system software consists of realtime monitor, Interrupt service routine and input/output handler. Each handler module is determind in order to control and monitor efficiently input/output device. Realtime monitor module is deter-mind in order to control efficiently computer environments and tasks. Interrupt service routines process multifariouse events which occur by chance using interrupt vector table. For demonstration control computer system, we have conducted a simulation and practiced with commercial HD64180 cpu board, A/D and D/A board, analog I/O board, digital I/O board and pluse board.
