ABSTRACT:
A system and method for processing multiple arbitrary sized data elements in a register. A method of the invention comprises the steps of: creating a mask register that defines a set of arbitrary sized segments for a register; storing a plurality of arbitrary sized data elements in a segmented data register arranged in accordance with the mask register, wherein the arbitrary sized data elements are sign extended; simultaneously operating on each of the of the data elements in the segmented data register to generate a set of resulting data elements in response to a machine instruction, wherein the resulting data elements depend on each other; and unpacking the resulting data elements to provide a plurality of arbitrary sized results that are independent of each other.
