Abstract

The present invention provides an apparatus and method for performing cryptographic operations on a plurality of message blocks within a processor to generate a message digest. In one embodiment, the apparatus includes translation logic and execution logic. The translation logic receives a cryptographic instruction from a source therefrom, where the cryptographic instruction prescribes generation of the message digest according to one of the cryptographic operations. The translation logic also translates the cryptographic instruction into a sequence of micro instructions specifying sub-operations required to accomplish generation of the message digest according to the one of the cryptographic operations. The execution logic is operatively coupled to the translation logic. The execution logic receives the sequence of micro instructions, and performs the sub-operations to generate the message digest.
