Preliminary Evaluation of a Digital Optical Systolic Processor Implemented with Acousto-Optic Cells
Abstract
Two multichannel acoustic-optic cells were imaged onto one another, and the output was optically summed to a linear photodiode array. By sending periodic data streams into this primitive processor and monitoring the output data stream, an evaluation was made as to the potential feasibility of this type of architecture. It was shown that a 630 million logical instructions per second processor was feasible. However, there is considerable overhead in implementing higher order functions such as addition and multiplication which reduced the computational capability to 4.5 million additions per second and 260 thousand multiplications per second.
