The technical result of the invention is that of reducing the number of intermediate sums and shifts performed in the hardware of digital computing devices during matrix multiplication. This technical result is achieved in that the claimed matrix multiplication method envisages using a lookup table in the form of a set of all the possible sums of the elements of the current row-vector of the first of the multiplied matrices, in which each element is present not more than once, and using bit slices of the current column-vector of the second of the multiplied matrices to request values from the lookup table, which can be efficiently obtained using a special type of memory referred to as a bit-based associative memory. The bit slices make it possible to select from the lookup table specific values which, having been shifted left by a number of steps equal to the number of the bit, sum to the desired value for an element of the resultant matrix corresponding to the indexes of the current vectors being processed.
