Abstract
Abstract An information processing apparatus has a plurality of nodes, a connection line for connection between the plurality of nodes, an arbiter for performing arbitration of use of the connection line, and an arbitration signal line for connection between the arbiter and each node, wherein the arbiter performs processing of a request for use of the connection line and processing of additional information related to data transfer executed after connection of the connection line. An arbitration method in the information processing apparatus includes steps of letting a node originating a request for use of the connection line, when requesting use of the connection line to the arbiter, also send additional information related to data transfer on the connection line together with the request for use to the arbiter; and letting the arbiter, when performing arbitration of use of the connection line to set the connection line based on the request, send the additional information related to the data transfer to a node being to receive the request.
