DMA Transfer from Labview app to Embedded Board.

[jon]

Hello,

I would like to perform a complete RAM test on an embedded Texas
Instruments board with 2 DSPs and 32MB RAM. The test equipment is
composed by the embedded unit, an "Spectrum Digital" emulator (usb
connection) and a PC with Labview 8.2, DSP Integration Toolkit for
Labview and Code Composer Studio 3.1.

I've achieved to fill the RAM but it's a very expensive and slow
transfer. It is possible to program a DMA in Labview in order to
lighten the download/upload operation?

Many Thanks In Advance.

Hi Jon,

Unfortunately the DSP Test Integration Toolkit is no longer officially supported and we do not have anyone trained in it. With that said, here are some resources that we do have available online:

Hope that helps. Best of luck in your application.

Best regards,
