Abstract: An element selection unit (200) and a method therein for vector element selection. The element selection unit comprises a selector control circuit (404) and a selector data path circuit (406), which data path circuit comprises a plurality of layers of multiplexers. The element selection unit further comprises a receiving circuit (401) configured to receive an instruction to perform a selection of elements from an input vector. The selector control circuit (404) is configured to generate a multiplexer control signal for each multiplexer based on a bit map and on a plurality of relative offset values. The data path circuit is configured to propagate the elements comprised in the input vector through the plurality of layers of multiplexers towards an output vector based on the generated multiplexer control signals. The data path circuit is further configured to write the propagated elements to enabled elements of the output vector.
