Abstract:

Under this contract, we have designed and implemented an optoelectronic cache memory and interface to a page oriented optical memory system. This work demonstrated that an optical memory can be tightly integrated into a conventional computer and that its high spatial bandwidth can be successfully exploited when optical memories are used as a backing store. Programs, executing on a host connected to this type optoelectronic interface, can transparently access data from the optical store with average access time faster than disk based electronic storage systems. This technology enables the use of large page oriented optical memories in applications such as medical, image, and geo-spatial databases where high speed access to page structured data is essential.
