Abstract

A novel architecture based on optical technology is presented for constructing parallel computers. The architecture exploits optics for its ultra-high speed, massive parallelism, and dense connectivity. The processing is based on a new technique called 2-D symbolic substitution which can be implemented with very fast optical components. Two-dimensional symbolic substitution algorithms are developed for arithmetic/logic operations as well as for complex scientific computations such as matrix algebra and FFT. The predicted performance of the system is compared with the performance of existing electronic array processors and is shown to be potentially superior. The bit-plane architecture is shown feasible and economical based on state-of-the-art optical and electro-optical technologies.
