Abstract : A digital multiplication by analog convulsion algorithm is extended by a hybrid combination of both floating and fixed-point arithmetic. An acousto-optical time-integrating architecture uses a binary representation of the hybrid combination of floating and fixed-point arithmetic. An array of full adders in conjunction with a photodetector array avoids generating mixed binary outputs that normally result when the digital multiplication by analog convolution algorithm is applied so as to eliminate the need for analog-to-digital converters otherwise needed to convert mixed binary to pure binary.
