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.
