Apparatus for transposing digital data

A digital storage device is provided that includes a storage unit having a plurality of word storage locations, each of the word storage locations being coupled to a corresponding read enable line and write enable line, and a pointer unit for addressing the read enable lines and the write enable lines to permit data to be written into the word storage locations in a first sequence in a first operating mode and to be retrieved from the word storage locations in a second sequence that is transposed from the first sequence in a second operating mode; and a clock generator coupled to the pointer unit which controls the operation of the pointer unit.
