Abstract
A large-scaled interconnection switch in which a plurality of data processors are interconnected to perform data transfer between one another. The switch includes communication controllers, one provided for each of the plurality of data processors, divided into groups, for controlling communication between the data processors. Each group of communication controllers is connected by a signal line having a multiple bit width. A switch arbiter for arbitrates switch setting requests for interconnection of the data processors from the communication controllers to output a switch setting control signal. The switch also includes bit slice switches having a predetermined bit division count and to which respective/output signal lines are connected which bit-divide input/output signals of the communication controllers. The bit slice switch receives a switch setting control signal from the switch arbiter and transfers data from a transmission data line from a communication controller to a receiving data line to the communication controller on the basis of the switch setting control signal.
