A feasibility study of the LARPBS optical bus model

Juan Rene Roldan, University of Texas at El Paso


Parallel processing systems require interconnections capable of handling high data rates in order to satisfy the communication demands of applications. The data rates that electrical data buses can handle may not be sufficient for some types of data interactive applications. Optical technologies have been proposed to address this limitation of electrical bus systems. During the past decade, several optical bus parallel models have been proposed. This thesis evaluates the practical nature of such optical bus models. Specifically, this thesis reports on optical power and signal loss in the Linear Array with a Reconfigurable Pipelined Bus System (LARPBS). A model that assists the calculation of signal losses in the LARPBS is presented together with four case studies. A straightforward implementation of the bus model suggests high losses that limit the number of processors supported. Nevertheless, this work also suggests that variations in the architecture may lead to more practical parallel systems.
