Abstract
A pipeline-controlled data processing system includes decoding apparatus for decoding successive instructions and a detection device responsive to the decoding apparatus output for determining when a particular two-instruction sequence is present. When a first instruction calls for an operation to be executed and the execution result to be loaded into an arithmetic register, and when a second instruction immediately following the first instruction calls for the storing of the output of the arithmetic register into both a main memory unit and a cache memory, the execution result is simultaneously stored in all of the arithmetic register, main memory and cache memory.
