Abstract
A matrix operation apparatus for performing a matrix operation at high speed and in a wide dynamic range, i.e., high precision, wherein an input vector is displayed with radiance of pixels, a display image is replicated through an optical system, component multiplications and partial summing between rows or columns of the matrix and the input vector are simultaneously performed by a transparent/opaque mask representing a binary-valued matrix component and a photosensor, parallel channels, each assigned to different bit of the matrix component calculates the partial sums and a power-of-2 scaling summer connected to the parallel channels electrically produces components of an output vector.
