Abstract: A processing system includes a content addressable memory (CAM) in an input/output path to selectively modify register writes on a per-pipeline basis. The CAM compares an address of a register write to an address field of each entry of the CAM. If a match is found, the CAM modifies the register write data as defined by a function for the matching entry of the CAM. In some embodiments, each entry of the CAM includes a data mask defining subfields of the register write data, wherein each subfield includes subfield data including one or more bits.
