The Evaluation Process

The ADSP-21479 EZ-Board evaluation board, as shown in Figure 2-11, provides developers with a low cost platform for initial evaluation of the ADSP-2147x SHARC processors via an external JTAG emulator or stan- dalone debug agent board.

To debug, you must have a debug agent board or emulator. The EZ-Board has an expansion interface that allows for modularity with different EZ-Extender boards.
