Apparatuses for reordering a plurality of data elements that utilize a buffer capable of storing at least one data element. The last data element (Pn) is located and moved to the buffer. The data element (Px) that should be located at the location of the last data element (Pn) is moved to fill the space vacated. If the last data element should be located at the location of Px, then the last but one (Pn−1) element is located and moved to the buffer. The element (Px′) that should be located at the location of Pn−1 is then moved to the location of Pn−1. The process is repeated until all the data elements are reordered.
