Instruction and logic to provide vector horizontal majority voting functionality

A non-transitory machine-readable medium having a first executable instruction stored therein that, when executed by a machine, causes the machine to:

• read a number of values from a portion of a plurality of data fields in a source operand specified by the first executable instruction, wherein the data fields store values of masked and unmasked vector elements, and wherein the number corresponds to a same number of the unmasked vector elements according to a mask specified by the first executable instruction;
• compute a result value to represent a majority of the number of the values read from the portion of the data fields in the source operand;
• and
• store the result value in a destination operand specified by the first executable instruction.

A processing system comprising:

• a memory;
• and
• a plurality of processors, wherein each of the plurality of processors comprises:
• a vector register comprising a plurality of data fields to store values of vector elements;
• a decode stage to decode a first instruction specifying:
• a destination operand, a size of the vector elements, a portion of the data fields, and a source operand;
• and
• an execution unit, responsive to the decoded first instruction, to:
• read a number of values from data fields of the size of the vector elements in the source operand;
• and
• store a result value in the destination operand specified by the first instruction, wherein the result value is computed from most common values read from the number of the values from the data fields of the source operand.

A method comprising:

• read a number of values from a portion of a plurality of data fields in a source operand specified by a first executable instruction, wherein the data fields store values of masked and unmasked vector elements, and wherein the number corresponds to a same number of the unmasked vector elements according to a mask specified by the first executable instruction;
• compute a result value to represent a majority of the number of the values read;
• and
• store the result value in a destination operand specified by the first executable instruction.
