Abstract: A processor to perform a string comparison instruction. The processor includes a decoder to decode the string comparison instruction. The packed comparison instruction is to have an immediate that is to be used to control performance of the string comparison instruction. The immediate includes a first set of two bits, a second set of two bits, a third set of two bits, and a fourth bit. The processor also includes an execution unit coupled with the decoder to execute the packed comparison instruction.

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.

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 determine whether each 32-bit floating point data element of first and second SIMD floating point operands is valid, compare only valid 32-bit floating point data elements of the first 64-bit SIMD floating point operand with only valid 32-bit floating point data elements of the second 64-bit SIMD floating point operand in the same data element position, and store indicators of whether the compared valid 32-bit floating point data elements of the first and second 64-bit SIMD floating point operands are equal.

Abstract: Method, apparatus, and program means for performing a string comparison operation. 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.
