<p>PURPOSE:To automate a multisystem computer system by providing an intersection connecting circuit capable of controlling bus switches and by supplying electric power to respective parts in parescribed sequence when the indication of system power feed is sent to the circuit. CONSTITUTION:Buses A-D connected to central processors 1-A-1-D and branch buses E-I are arranged intersecting mutually, and bus switches S11-S15...S41- S45 arranged at respective intersections are connected to intersection connecting circuit 2 via bus 8 for bus switch communication. To respective branch buses E- I, magnetic disk devices 3-A and 3-B, magnetic tape device 4, display 5, etc., are connected to constitute a multisystem computer system. Through power source control circuit 10, intersection setting table 11 and microprocessor 9 provided to circuit 2, the power is fed to respective system parts in prescribed sequence and at the point in time of the power feed, switches S11-S15-S41-S45are controlled.</p> |
