Transfer mechanism and load scheduling conflict - store its low cost and high speed

摘要

An object of the present invention is to improve the way you run the load and store instructions. A embodiments provide a method and apparatus for executing instructions. Step In one embodiment, the method of calculating receiving a load instruction and a store instruction, a store effective address of the store data for load effective address and the store instruction load data for the load instruction and, including the. The method further includes the steps of comparing the load effective address and the store effective address, store instruction for the store data store instruction from the first pipeline running load instruction second running of comprising a step of predicting forwards to the pipeline, the. Load instruction receives the store data from the first pipeline, to receive the requested data from the data cache. If you load the effective address matches the store effective address, the store data that is forecast to transfer it is integrated with the load data. If the load effective address does not match the stored effective address, the requested data from the data cache is integrated with the load data. .FIELD 2
