  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).
