  • Patent number: 10171231
    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.
    Type: Grant

  • Patent number: 9645821
    Abstract: A processor includes a decoder logic to decode a compare instruction, and an execution unit to execute the compare instruction. The compare instruction is to cause the processor to compare integer data elements of a first 64-bit SIMD integer operand with integer data elements of a second 64-bit SIMD integer operand. The integer data elements of the first 64-bit SIMD integer operand to be compared with the integer data elements of the second 64-bit SIMD integer operand are to be in same data element positions. The compare instruction is also to cause the processor to store a plurality of indicators of whether the compared integer data elements of the first and second 64-bit SIMD integer operands are equal. The plurality of indicators are expanded data elements, each of a first multi-bit size.
