| Abstract | A method of an aspect includes receiving an instruction indicating a first source packed memory indices, a second source packed data operation mask, and a destination storage location. Memory indices of the packed memory indices are compared with one another. One or more sets of duplicate memory indices are identified. Data corresponding to each set of duplicate memory indices is loaded only once. The loaded data corresponding to each set of duplicate memory indices is replicated for each of the duplicate memory indices in the set. A packed data result in the destination storage location in response to the instruction. The packed data result includes data elements from memory locations that are indicated by corresponding memory indices of the packed memory indices when not blocked by corresponding elements of the packed data operation mask. |
