To perform multiplication of matrices in a vector processing system, partial products are obtained by dot multiplication of vector registers containing multiple copies of elements of a first matrix and vector registers containing values from rows of a second matrix. The dot products obtained from this...
In one embodiment, a matrix-vector multiplication (MVM) component generates a product vector based on (i) an input matrix and (ii) an input vector. The MVM component has a permuter, memory, and an XOR gate array. The permuter permutates, for each input sub-vector of the input vector,...
