Abstract
A vector reduction instruction with non-unit strided access pattern is received and executed by the execution circuitry of a processor. In response to the instruction, the execution circuitry performs an associative reduction operation on data elements of a first vector register. Based on values of the mask register and a current element position being processed, the execution circuitry sequentially sets one or more data elements of the first vector register to a result, which is generated by the associative reduction operation applied to both a previous data element of the first vector register and a data clement of a third vector register. The previous data element is located more than one element position away from the current element position.
