ABSTRACT:
A system and methods are discussed for providing additional capabilities to some instructions associated with loop execution. A standard set of instructions is processed using only a standard instruction size. Some loop instructions are processed with a standard instruction portion of the standard instruction size and an augmented instruction portion. The augmented instruction portion provides additional capabilities associated with the standard instruction portion. The augmented instruction portion can provide capabilities associated with conditional execution of the standard instruction portion or other instructions within a program loop. Furthermore, the augmented instruction portion can provide an additional operand to be used with the standard instruction portion.
