Information processing apparatus for multiplex transmission of signals for arbitration and signals for data transfer.

摘要

An information processing apparatus has a plurality of computational nodes. Each computational node is provided with at least one wavelength multiplexer for multiplexing signals of a plurality of wavelengths and simultaneously transmitting the multiplexed signals and at least one wavelength demultiplexer for demultiplexing the transmitted signals in the plurality of wavelengths. The apparatus further comprises a concentrator connected through a transmission line medium with each of the plurality of computational nodes. The concentrator includes a wavelength demultiplexer for demultiplexing the signals of the plurality of wavelengths transmitted through the wavelength multiplexer from each of the plurality of computational nodes; a wavelength multiplexer for multiplexing signals of the plurality of wavelengths and simultaneously transmitting the multiplexed signals to each of the plurality of computational nodes; a connector for connection of a signal for data transfer between the plurality of computational nodes connected with each other; and an arbiter for performing an arbitration operation for use of the transmission line in the data transfer. A signal for arbitration for use of the transmission line transmitted between the computational nodes and the arbiter and the signal for data transfer between the computational nodes are transmitted in a multiplexed manner on the transfer line medium. <IMAGE>
