< 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).
