Database System Studies in Fine Grain Optoelectronic Computing.

Abstract

The main objective of this program was to investigate the design and the optoelectronic implementation of a high performance optical memory-processor interface for database applications. For very large database machines, in general, memory bandwidth is a bottleneck. Typically, the access time of a conventional secondary storage devices such as magnetic disks is at millisecond scale. The use of parallel access optical storage systems, such as parallel read-out optical disks and 2-photon 3D memories, have the potential of achieving enormous throughput (> 100 Chits/sec) and capacity (- 1 Tbits). In this research, we have studied the relational database architecture based on a bi-orthogonally accessed 2-photon 3D memory. Specifically, the database operation considered is the data filtering. Various optoelectronic technologies have been evaluated for interfacing parallel optic and electronic systems. The system performances have been measured in term of the areal data throughput and the energy required per transmitted data bit.
