Data Address Generator


Data Address Generator

(architecture)(DAG) The mechanism which generates temporarymemory addresses for data that is transferred between memoryand registers in a Digital Signal Processor.

Certain DSP architectures incorporate more than one DAG tosimplify the programming needed to move blocks of data betweenbuffers.

For instance, certain Fast Fourier Transform algorithmsrequiring 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).
