Abstract

PURPOSE: To obtain a peripheral device coupling unit which selects automatically various peripheral devices, by providing a means which discriminates the class of peripheral devices in a microcomputer and a minicomputer.
CONSTITUTION: Driving programs for peripheral devices AWD are stored in memory 40, and peripheral devices AWD are connected to connection part 20. A CPU calls peripheral device discrimination program X in memory 40 through address bus 2 by address selection circuit 135 and executes it. That is, the CPU outputs data to signal line 13 through address bus 22 and address selection circuit 111, and the class of peripheral devices is discriminated by peripheral device discrimination circuit 30 and is outputted to data bus 1. The CPU receives this signal to select peripheral devices to be conneted and calls and executes driving programs AWD in memory 40 for peripheral devices to be connected, thereby completing coupling with peripheral devices to be connected.
