Data Address Generator

   <architecture> (DAG) The mechanism which generates temporary
   memory addresses for data that is transferred between memory
   and {registers} in a {Digital Signal Processor}.

   Certain {DSP} architectures incorporate more than one DAG to
   simplify the programming needed to move blocks of data between
   buffers.

   For instance, certain {Fast Fourier Transform} {algorithms}
   requiring {bit reversing}, can use the DAG for that purpose,
   or they can use two DAGS, one for Program Memory Data (PMD),
   and the other for Data Memory Data (DMD).
