Abstract
A method, system and program for architecturally identifying data processor implementations are provided. The invention comprises assigning a plurality of least significant bits in a processor's identification register to a unique value. This value can be assigned to these bits permanently during manufacture and is used to identify the bit specification for a specific processor implementation. The present invention can be generalized to include any processor architecture that comprises a plurality of instruction subsets for different bit specifications.
