Abstract

PURPOSE: To increase the overall efficiency of computer system by performing resetting with hardware without the aid of program, through the selective reset for the I/O in the common input and output bus reserved by CPU.
CONSTITUTION: The reset signal emitted from CPU on P-BUS is delivered to I/O-BUS in the path of P-BUS→wind switch on P-BUS→wind switch on I/O-BUS. The reset signal is delivered to the I/O-BUS controller BC through the bidirectional reset line 10 provided every slot of I/O-BUS. BC receives this signal, and searches the CE on I/O-BUS used or reserved by CPU connected to the wind switch from the slot number mounting the wind switch through which the reset signal passes.
