Abstract: A method and apparatus are provided for target addressing and translation in a non-uniform memory environment with user defined target tags. The apparatus for target addressing and translation includes a processor and a first address translation unit coupled to the processor. The first address. translation unit translates an effective address (EA) to a real address (RA). The first address translation unit includes a target tag associated with each address translation. A second address translation unit translates a real address (RA) to a target address (TA). The second address translation unit includes a target tag associated with each address translation. A cache includes a cache directory and a target tag is stored into the cache directory with each cache fill.
