This EE-Note explains how you use the VisualDSP++® Expert DAI plug-in to configure the signal routing unit (SRU) in ADSP-2126x, ADSP-2136x, ADSP-2137x, and ADSP-214xx SHARC® processors. The Expert DAI plug-in simplifies the task of generating the C and/or assembly code that is used to program the SRU. The Expert DAI plug-in associated with this EE-Note can be used with the VisualDSP++® 6.2 and higher versions.
This document describes the Expert DAI plug-in, a tool designed to simplify the task of generating C and/or assembly code for programming the Signal Routing Unit (SRU) in specific SHARC processor families. The SRU establishes connections between peripheral inputs/outputs and external DAI pins based on configuration registers, allowing for flexible system interconnection.
The guide details the installation process for the plug-in within the VisualDSP++ environment and provides step-by-step instructions for using the graphical user interface to configure signal routing. It includes examples of generating code for specific processor models, such as the ADSP-21262 and ADSP-21367, demonstrating how to map signals like clock, frame sync, and data lines to various peripherals and pins.
The tool is compatible with VisualDSP++ versions 3.5, 4.0, 4.5, and 5.0.
You must type regsvr32.exe AdvancedExpertDAI.dll from the System directory.
The destination signals do not appear in the routing diagram, and you must click the pin to view them.
