Method and system for early instruction text based operand store compare reject avoidance
Abstract:
A method and system for early instruction text based operand store compare avoidance in a processor are provided. The system includes a processor pipeline for processing instruction text in an instruction stream, where the instruction text includes operand address information. The system also includes delay logic to monitor the instruction stream. The delay logic performs a method that includes detecting a load instruction following a store instruction in the instruction stream, comparing the operand address information of the store instruction with the load instruction. The method also includes delaying the load instruction in the processor pipeline in response to detecting a common field value between the operand address information of the store instruction and the load instruction.
