Abstract
A processor includes a vector register including data fields to store values of vector elements of data, a decoder to decode a single instruction multiple data (SIMD) instruction specifying a source operand and a mask to identify a masked portion of the data fields. An execution unit is to read a plurality of values from unmasked data fields of the plurality of data fields of the vector register; compare, within the vector register, each of the plurality of values from the unmasked data fields for equality with all other values of the plurality of values; and responsive to a detection of an inequality of any two values of the plurality of values, set a mask field, corresponding to a detected unequal value, to a masked state with a flip of a bit value of the mask field, to signal the detection of the inequality.
