Zusammenfassung:A method and system of controlling out of order execution pipelines using pipeline skew parameters is disclosed. The pipeline skew parameters track the relative position of a load/store instruction in a load/store pipeline and a simultaneously issued integer instruction in a variable length integer pipeline. The pipeline skew parameters are used to improve data hazard detection, pipeline stalling, and instruction cancellation.
