1. An apparatus for performing cryptographic operations, comprising: a cryptographic instruction, received by a computing device as part of an instruction flow executing on said computing device, wherein said cryptographic instruction prescribes one of the cryptographic operations; translation logic, operatively coupled to said cryptographic instruction, configured to translate said cryptographic instruction into micro instructions, wherein said micro instructions are ordered to direct said computing device to load a second input text block and to execute said one of the cryptographic operations on said second input text block prior to directing said computing device to store an output text block corresponding to a first input text block; whereby said output text block is stored during execution of said one of the cryptographic operations on said second input text block.
