ABSTRACT:
A matrix arithmetic apparatus which comprises a plurality of exclusive memories provided correspondingly to the respective items of a matrix or vector each including a plurality of elements in order to store element data corresponding to the elements. An arithmetic operation of Y=A.multidot.X+B is carried out with respect to the element data read out the memories wherein multiplication (A.multidot.X) and addition {(A.multidot.X)+B} of data representing the respective elements are undertaken by the exclusive arithmetic units by a pipe line system. Internal address computers corresponding to the memories are provided in order to determine a memory address of each of the memories from which a stored data is to be read out.
