NI LabVIEW toolkit simplifies design validation and debugging of TI DSPs

5 November 2003 Design Automation

National Instruments has released to market the LabVIEW DSP Test Integration Toolkit 2.0, a LabVIEW add-on that integrates with Texas Instruments Code Composer Studio (CCStudio) Development Tools.

This toolkit simplifies debugging and validation of code executing on TI TMS320 digital signal processors (DSPs) with an executable that design engineers use to establish communication and control of data internal to DSPs in seconds. The executable runs parallel to CCStudio and uses the realtime data exchange (RTDX) communication protocol.

"We created the RTDX data link to help CCStudio users better understand how their DSPs will perform in realtime without halting their processors," said Raj Agrawala, C5000 product marketing manager at TI. "Now, with LabVIEW DSP Test Integration Toolkit 2.0, our customers can more easily access this technology to verify their DSP designs and turn out high-quality products faster."

Using RTDX, engineers can view and control DSP test data in realtime at speeds of up to 2 MBps. Engineers typically spend hours or days programming custom applications to communicate to the DSP through RTDX. With the LabVIEW DSP Test Integration Toolkit, engineers no longer need to program to facilitate this communication; they simply drop controls and indicators onto the executable front panel and configure the objects with a few mouse clicks. Additionally, engineers can increase the functionality and flexibility of their systems by using RTDX VIs in LabVIEW where they can customise controls and indicators on the LabVIEW front panel and incorporate data simulation and analysis using LabVIEW.

With the latest version of the LabVIEW DSP Test Integration Toolkit, engineers also can read and write data directly to the DSP memory using LabVIEW for traditional, non realtime debugging. By using LabVIEW, they can take advantage of advanced data visualisation capabilities for viewing waveforms, video signals, scalar values and other data. Engineers can complete their DSP debug systems by connecting LabVIEW to a wide range of instruments including signal generators, digitisers, multimeters and more.
