Data Address Generator definition
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).
