Abstract
The instruction register (IR), of a data processing system, stores a program instruction during at least an initial operation code decoding phase to initiate execution of the instruction. The IR (13) has a number of input gates in addition to the input gates from a program storing main storage device. The additional input gates respond to control or logic signals for gating information from the data flow hardware (40) to the instruction register.
