Abstract: A flexible aes instruction set for a general purpose processor is provided. The instruction set includes instructions to perform a “one round” pass for aes encryption or decryption and also includes instructions to perform key generation. An immediate may be used to indicate round number and key size for key generation for 128/192/256 bit keys. The flexible aes instruction set enables full use of pipelining capabilities because it does not require tracking of implicit registers.

Abstract: A machine-readable medium may have stored thereon an instruction, which when executed by a machine causes the machine to perform a method. The method may include combining a first operand of the instruction and a second operand of the instruction to produce a result. The result may be encrypted using a key in accordance with an Advanced Encryption Standard (AES) algorithm to produce an encrypted result. The method may also include placing the encrypted result in a location of the first operand of the instruction.

Abstract: Method, apparatus, and program means for performing a string comparison operation. In one embodiment, an apparatus includes execution resources to execute a first instruction. In response to the first instruction, said execution resources store a result of a comparison between each data element of a first and second operand corresponding to a first and second text string, respectively.
