Abstract
The present invention provides a multiple bus control device and others which can also be applied to access control by a signal having a directional propagation property for implementing various communication between/among modules. Each of plural modules makes a request for communication to a multiple bus control device by sending communication request information for specifying one or more communication partner modules to the multiple bus control device. The multiple bus control device checks an idle state of a module to be communicated and an idle channel in a multiple bus based upon received communication request information and permits communication between a module which sends communication request information using the idle channel and a communication partner module specified in the communication request information.
