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.
