Abstract
One aspect of the invention relates to a super scalar processor having a memory which as addressable with respect to the combination of a page address and a page offset address, and provides a method for detecting an overlap condition between a present instruction and a previously executed instruction, the previously executed instruction being executed prior to execution of the present instruction. In one embodiment, the method comprises the steps of dividing the present instruction into a plurality of aligned memory accesses; determining the page offset for at least one of the aligned accesses; and comparing the page offset and byte count for the present instruction to a page offset and byte count for the previously executed instruction.
