METHOD AND DATA PROCESSOR FOR REDUCED PIPELINE STALLING

摘要

A data processor (200) has a pipelined execution unit (120). Whether a first instruction is one of a class of instructions wherein as a result of execution of the first instruction the contents of an operand register will be stored in a destination register is determined. A second instruction that references the destination register is received before a completion of execution of the first instruction. The second instruction is executed using the contents of the operand register without stalling the second instruction in the pipelined execution unit (120).
