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).
