Abstract
The described embodiments provide a processor for generating a result vector with summed values from a first input vector. During operation, the processor receives the first input vector, a second input vector, and a control vector. When generating the result vector, the processor first captures a base value from a key element in the second input vector. The processor then writes the sum of the base value and values from relevant elements in the first input vector into selected elements in the result vector. In addition, a predicate vector can be used to control the values that are written to the result vector.
