An information processing apparatus executes a machine language instruction according to a microprogram controlling method. The apparatus comprises an instruction decoder for decoding the machine language instruction; an operand controller for receiving from the instruction decoder, information about operands that are necessary in executing the machine language instruction, and fetching and holding the operands according to the information; and an instruction executing device generating operand requests to the operand controller, obtaining the operands, and executing the machine language instruction under the control of a microprogram. Thus, the apparatus can execute a plurality of machine language instructions that respectively prescribe the same operation to be carried out on the different kinds of operands, under the control of a single microprogram irrespective of the differences of the kinds of the operands.
