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.

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: An Advanced Encryption Standard (AES) key generation assist instruction is provided. The AES key generation assist instruction assists in generating round keys used to perform AES encryption and decryption operations. The AES key generation instruction operates independent of the size of the cipher key and performs key generation operations in parallel on four 32-bit words thereby increasing the speed at which the round keys are generated. This instruction is easy to use in software. Hardware implementation of this instruction removes potential threats of software (cache access based) side channel attacks on this part of the AES algorithm.
