serve as an introduction to using RTDX technology from Texas Instruments with Simulink for the purpose of verifying that that your Simulink simulation is running the same way as your DSP implementation. You will need R2006a+ or greater. R2006a will not work.
There is a readme.doc and that is the best place to get started.
The rtdx_intro.doc file is a good place to start for an introduction to the application of RTDX for verification purposes.
There are two main RTDX/Simulink applications. One is for a simple Simulink model containing only a gain block and the second one is a more involved noise cancellation application.
By all means, use the HTML web-based example selectors to navigate thru the many files. You will find this far easier than opening individual models from Matlab. The readme.doc file will describe this process.
