DEVICE FOR MULTIPLYING NUMERIC MATRICES Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: device has picture-type shift register with spatial right-hand shift of pictures, first parallel input, second group of L parallel inputs, L picture-type D flip-flops, L units for picture logical multiplication involving pre-formation of input operands with respective first and second parallel optical inputs and outputs, group beam combiner picture-type analog-to-digital converter with parallel optical input, picture accumulator with parallel input and p parallel outputs. Device is characterized by high structural speed which makes up T=N²(2L-1)ΔT processing time steps (N and L are, respectively, column lines and binary bit edges of source numeric matrix representation) and organization of parallel input-output of source and resultant matrices affording matching of forms and structures of input and output data representation. EFFECT: improved speed, enlarged functional capabilities. 4 cl, 11 dwg, 6 tbl
