Low Level Signal Processing for the Optoelectronic Memory System Interface

Abstract : This report describes the development and implementation of channel coding and error detection firmware and software for a prototype optical memory system. Specific accomplishments include the development and implementation of a novel 2D coding system for managing inter-symbol interference in page oriented memory as well as clock extraction, noise filters, 5-7 coder firmware for the memory prototype. Software and firmware implementation of spectral Reed- Solomon error correcting codes were also developed and incorporated into a demonstration system. Additionally, we have identified transaction-level processing primitives that might be implemented at the storage interface to improve utilization of the high transfer rate data for image storage applications.
