Abstract
A method, processor and/or system for processing data is disclosed that in an aspect includes providing a physical register file with one or more register file entries for storing data; identifying each physical register file entry with a row identifier to identify the entry row in the physical register file; enabling one or more columns within a target entry row of the physical register file; and revising data in the columns enabled within the target entry row of the physical register file. In an aspect, each physical register file entry is partitioned into a plurality of columns having a bit width and a column mask preferably is used to enable the one or more columns within the target row of the physical register file, and data is revised in only the columns enabled by the column mask.
