System having user programmable addressing modes and method therefor

摘要

A system (10) implements user programmable addressing modes in response to control information contained within an input address. Encoded control information stored in a plurality of user programmed address permutation control registers (70-72) is used to determine what bit values are used to replace predetermined bits of the input address to selectively create a corresponding permutated address. Since no modification to a processor's pipeline is required, various permutation addressing modes may be user-defined and implemented using either a general-purpose processor or a specialized processor.
