SYSTEM SWITCHING CONTROLLER

摘要

PURPOSE:To simplify the processing by switching an input/output switch device independently for each device, each group or en bloc. CONSTITUTION:The input/output switch information 20 given from a central processor is stored in a register 101 in a system switch controller 1. An input/ output switch device indicating circuit 103 decodes an address part 203 of the information 20 stored in the register 101 and then gives an indication to a switch control signal transmission circuit 104 to send an input/output switch control signal only to the input/output switch device that is designated by lower two bits for example. While an input/output switch information transmission circuit 102 informs that the input/output switching is carried out.
