Abstract

A new computer architecture using multi-wavelength optoelectronic integrated circuits (OEICs) is proposed to attack the problems caused by interconnection complexity. Multiwavelength.OEIC architectures, where various wavelengths are employed as information carriers, provide wavelength as an extra dimension of freedom for parallel processing, so that we can perform several independent computations in parallel in a single optical module using the wavelength space. This `multiplex computing' enables us to reduce the wiring area required by a network and improve their complexity. In this paper, we discuss the efficient multiplexing of Batcher's bitonic sorting networks, highly parallel computing architectures that require global interconnections inherently. A systematic multiplexing of interconnection topology is presented using a binary representation of the connectivities of interconnection paths. It is shown that the wiring area can be reduced by a factor of 1/r2 using r kinds of wavelength components.
