In some examples, the single instruction includes fields for an opcode, one or fields to reference a first source operand, one or fields to reference a second source operand, one or fields to reference a destination operand, wherein the opcode is to indicate that execution circuitry is, in response to a decoded instance of the single instruction, to at least: perform a prefix sum by for each non-masked data element position of the second source operand adding a data element of that data element position to each data element of preceding data element positions and adding at least one data element of a defined data element position of the first source operand, and store each prefix sum for each data element position of the second source operand into a corresponding data element position of the destination operand.
