Abstract
The described embodiments provide a processor for generating a result vector with shifted values. During operation, the processor receives a 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 position in the second input vector. The processor then determines a number of bit positions to shift the base value using selected relevant elements in the first input vector. The processor then shifts the copy of the base value by the number of bit positions and writes the value into a corresponding element in the result vector. In addition, a predicate vector can be used to control the values that are written to the result vector.
