A microprocessor, having a memory element containing a plurality of multi-bit instruction words, an arithmetic logic (ALU) unit coupled to the memory element and responsive to at least a portion of each of the instruction words for performing data manipulations, and a controller for generating address signals that are communicated to the memory element to cause sequential access of the instruction words, includes a storage element that interconnects certain of the signal lines that communicate the instruction words to the ALU to the controller. In response to a first predetermined instruction word the storage element receives and stores the portion of the instruction word being conducted to the ALU. In response to a second predetermined instruction word, the content of the storage element is transferred to the controller to form an address signal.
