Paper Abstract

Interconnection architectures are a cornerstone of parallel computing systems. However, interconnections can be a bottleneck in conventional computer architectures because of queuing structures that are necessary to handle the traffic through a switch at very high data rates and bandwidths. These issues must find new solutions to advance the state of the art in computing beyond the fundamental limit of silicon logic technology. Today's optoelectronic (OE) technology in particular VLSI/FLC Spatial Light Modulators (SLMs) can provide a unique and innovative solution to these issues. This paper will report the motivations for the system, describe the major areas of architectural requirements, discuss interconnection topologies and processor element alternatives, and document an optical arbitration (i.e., control) scheme using 'smart' SLMs and optical logic gates. The network topology is given in Section 2.1 Architectural Requirements - Networks, but it should be noted that the emphasis is on the optical control scheme (Section 2.4) and the SYSTEM.
