New optical matrix-vector multiplier
Abstract
Whitehouse and Speiser (1977) have pointed out that two numbers may be multiplied by convolving their binary representations. As convolution can be conveniently performed with the aid of optical operations, analog optical processors are inherently suited for the performance of digital operations. This situation has led to the design of optical computer architectures. These architectures utilize time-domain correlators which integrate either in time or space. The present investigation is concerned with a new architecture based on a space-integrating optical correlator. The employed space-integrating multiplier may be used in a systolic fashion to perform a full matrix-vector multiplication.
