摘要： A method is described that performing an image integral calculation by creating a second vector and creating a third vector. The second vector is created by executing a first instruction that adds alternating elements of a first vector to respective neighboring elements of the first vector and presents resulting summations into said second vector. The first instruction also passes through the respective neighboring elements to said second vector. The third vector is created by executing a second instruction that adds elements of one side of the second vector to an element of another side of the second vector and passes through the another side of the second vector.
