Abstract
Various encoding schemes are discussed for more efficiently encoding instructions which identify first and second architectural register numbers. In the first example, by constraining the first architectural register number to be greater than the second architectural register number, this frees up encodings for use in encoding other operations. In a second example, the first and second architectural register numbers may take any value but one of a first type of processing operation and a second type of processing operation is selected depending on a comparison of the first and second architectural register numbers.
