DSP gets a toolkit

Engineers can now integrate National Instruments’ LabVIEW graphical development environment with Texas Instruments’ Code Composer Studio development tools.

With National Instruments’ new LabVIEW DSP Test Integration Toolkit, engineers can integrate the company’s LabVIEW graphical development environment with Texas Instruments’ Code Composer Studio development tools, reducing testing and development time of TI’s digital signal processing (DSP) systems.

Because testing early in the design process of DSP systems was traditionally complex and time consuming, design engineers often delayed validation until after system prototypes were built. With this toolset, engineers can use LabVIEW to identify design flaws prior to prototype construction, reducing time to market and improving the quality of products that use DSP chips.

The LabVIEW DSP Test Integration Toolkit gives engineers a graphical tool to build DSP test and verification systems. As an eXpressDSP-compliant plug-in, the toolkit automates routine functions in Code Composer Studio, such as ‘build’ and ‘run,’ and communicates test data directly to and from the DSP chip’s memory. Using LabVIEW, engineers can read and write data internal to the DSP chips and can view and control test data in real time at speeds of up to 2 MB/sec using TI’s RTDX data link.

Because LabVIEW can be integrated with a variety of measurement I/O, engineers can generate real-world stimuli and take real-world measurements to compare with theoretical data. They then can correlate operating parameters of DSP algorithms with the actual effects seen on the input and output to the DSP and adjust system parameters dynamically, thus speeding testing and verification phases of code development.

The LabVIEW DSP Test Integration Toolkit works with the TMS320C6000, TMS320C5000, TMS320C2800, and OMAP platforms. Users must use LabVIEW 6.1 and Code Composer Studio 2.1 or higher with the toolkit.
