labview dsp module with tidsk 6713

[Arpine_Soghoyan]

Hi,

I'm working with TI DSK6713 board on Labview 8.6.1 version with the Labview dsp module 8.6.

The idea is to delegate computationally heavy FFT operation to DSP processor computing it many times in a loop.

As FFT is tailored for DSP and, in fact, Labview DSP tool has build-in FFT module, it should operate much
faster on DSP rather PC. So I expect to have acceleration here, and I don’t see that so far.

Does anyone observe performance accelaration with labview dsp compared to labview only performance ? What are the tools for measuring timing statistics on labview dsp ? 

Thanks.

Hey Salander,

I am an applications engineer here at National Instruments and would like to get a little more information from you to see if I can help you with your issue. I am not particularly familiar with the TI DSK6713 as it is a third party product. It seems to me like you think that since the TI DSK6713 has a DSP processor it should hypothetically run LabVIEW DSP faster than your PC. I am wondering if the TI DSK6713 is fundamentally different than any other board. 

Here is a link to the manual for LabVIEW DSP that might have some helpful information for you that could shed some light on your issue:
