Overview

The LabVIEW DSP Test Integration Toolkit accelerates DSP development with real-time communication through Texas Instruments' (TI) Code Composer StudioTM and DSP technology. The LabVIEW DSP Test Integration Toolkit leverages TI's Real-Time Data ExchangeTM (RTDXTM) software technology to interactively control and display running DSP applications using LabVIEW's professional user interface tools and the LabVIEW RTDX VIs.

Note: The DSP Test Integration Toolkit is no longer officially supported by NI, but you can download the VIs that were included in this toolkit.

Introduction

In this demonstration, a TI 6711 DSK inputs an audio signal and uses a Finite Impulse Response (FIR) filter to filter an additive noise input. The LabVIEW DSP Test Integration Toolkit adds noise to the input signal, adjusts the FIR filter parameters while the DSP is running, and displays the filtered response.

In Code Composer Studio, several RTDX channels have been defined to transfer data to and from Code Composer Studio. This transfer allows the adjustment of filter coefficients and returns the filtered response to LabVIEW without interrupting processing on the DSP. You can then use any of the 400+ analysis VIs in LabVIEW to perform additional analysis on the signals.


The LabVIEW DSP Test Integration Toolkit includes the LabVIEW Debugging Workbench for RTDX Communication, which provides a way to debug and control a program on the DSP without doing any LabVIEW programming. The LabVIEW Debugging Workbench for RTDX Communication communicates with existing RTDX channels defined in the CCS project.
