Paper Abstract

A challenging task facing the designers for the next generation of archival storage system is to provide storage capacities several orders of magnitude larger than existing systems while maintaining current data access times. To meet this challenge, a CMOS optoelectronic database filter suitable for large capacity relational database systems that use page-oriented optical storage devices has been developed. Based on a smart-pixel strategy, the filter performs optical-to-electrical data conversion, processes database query operations and only passes the data matching a query to the host computer. The photonic VLSI chip monolithically integrates a smart-pixel array that incorporates page-oriented optical reading, data manipulation logic, data buffering, and filter control circuitry for interfacing the filter chip with an electronic host computer. The database filter can offset the bandwidth mismatch without loss of valid data or significant delay in data access. A software simulator is developed to simulate the behavior of the database filter. The implementation and performance analysis of a 32 x 32-bit database filter fabricated through a 0.35-micron CMOS process is reported.
