ABSTRACT:
In the data processing apparatus utilizing the pipeline control, an OSC detect circuit detects that the execution result of a store-type instruction whose store operation has not been completed is utilized as an operand of a fetch-type instruction which succeeds the store-type instruction. When the OSC detect circuit detects an OSC and a store operation of a preceding store-type instruction is executed, the data processing apparatus aligns the operand position with the operand fetched by the fetch-type instruction and merges the store operand.
