LabVIEW-Based Power Measurement Tool Profiles Power Consumption of DSP Chips

7/2/2004 - National Instruments announced the LabVIEW-based Power Measurement Tool designed to evaluate power consumption of three new low-power digital signal processor (DSP) chips from Texas Instruments. The Power Measurement Tool consists of bundled NI data acquisition hardware and LabVIEW-based executable software. Using this tool, design engineers can more quickly validate power consumption of DSP designs for personal electronics, medical devices and other products that require low power consumption.

“Design engineers can use the LabVIEW-based Power Measurement Tool to accurately profile power consumption based on actual application behavior, including I/O power usage,” said Leon Adams, worldwide DSP product marketing manager, Texas Instruments. “This helps them more quickly iterate through a low-power tuning process and deliver their products to market sooner.”

With the Power Measurement Tool, engineers can measure and analyze power consumption of their product designs. For more visibility into their code, they can combine the tool with the NI LabVIEW DSP Test Integration Toolkit, a LabVIEW add-on that integrates with TI Code Composer StudioTM. Using the toolkit, engineers can control code execution, load algorithms onto the DSP and control real-time DSP data – including waveforms, video, and scalar values – with code developed in Code Composer Studio while using the Power Measurement Tool to profile the power consumed.

The LabVIEW-based Power Measurement Tool is part of the National Instruments ongoing commitment to providing graphical development tools for DSP design and test engineers. The Power Measurement Tool complements the recent NI acquisition of Hyperception, a software company specializing in graphical tools for programming DSPs. Future NI initiatives will further simplify DSP software development for signal processing solutions and expand the reach of DSP technology to a broad range of new users and application areas.

The NI LabVIEW executable and data acquisition hardware bundle is available from Spectrum Digital, Engineers can use the Power Measurement Tool with the TI TMS320C5509A evaluation module, also available from Spectrum Digital, to develop power-sensitive applications with the TI TMS320C5509A, C5507 and C5503 DSPs and to take advantage of the new eXpressDSPTM power design tools from TI.
