Abstract: Method and apparatus including a system of integrated ciruit devices for executing matrix operations of the form [A] operated upon by [B] equals [C], where [A], [B] and [C] are each a matrix having a plurality of elements expressed in either unsigned or in two's complement format. The system includes at least one first array of data storage means organized as (j) physical rows and (k) physical columns of bits for providing storage for one bit of each of a plurality of elements of a row vectors of the matrix [A], an individual one of the (j) rows having bits of the same binary weight. The system further includes at least one second array of data storage means organized as (m) physical rows and (n) physical columns of bits, an individual one of the (m) rows storing a same binary weight bit or each of a plurality of elements of a column vector of the matrix [B].
