Abstract
Methods and systems for controlling writing to register files in a processing system having at least two execution pipelines are provided. Aspects include obtaining a micro operation for execution by an execution unit of a first pipeline in the processing system, wherein the micro operation includes writing data to a register file. Aspects also include determining whether the data will be accessed by an execution unit of a second pipeline in the processing system. Based on a determination that the data will only be accessed by the execution unit of the first pipeline, aspects include blocking writing of the data to a register file of the second pipeline.
