Abstract:
The present invention relates to a method for the unification of PER branch and PER store operations within the same dataflow. The method comprises determining a PER range, the PER range comprising a storage area defined by a designated storage starting area and a designated storage ending area, wherein the storage starting area is designated by a value of the contents of a first control register and the storage ending area is designated by a value of the contents of a second control register. The method also comprises retrieving register field content values that are stored at a plurality of registers, wherein the retrieved content values comprises a length field content value, and setting the length field content value to zero for a PER branch instruction, thereby enabling a PER branch instruction to performed similarly to a PER storage instruction.
