Abstract
PURPOSE: To automate power on and off of each device sconstituting an information procesing system, by geneating power on and off signals and by generating an interrupting signal requesting the start up operation.
CONSTITUTION: A system power supply control device 101 has a generating circuit of power-on and power-off signals for each device constituting the system, a generating circuit of the first interrupting signal reqesting the start up operation and the second interrupting signal reqesting the start of an information protecting program, etc. The system power control device 101 is connected to devices (CPU, MEM and IOM) constituiting a processor 102 and peripheral devices 107 through separate signal cables L, LW where the power-on signal, the power-off signal, the READY signal indicating the availability of devices, the power-off request signal, etc. come and go. By this constitution, it is possible to automate power on and off of each device constituting the information processing system.
