Best hardware FIR example

Hi Michael,

Few examples for using FIR H/W on ADSP-21469 are availablle with the VisualDSP installation at path below:

....Program Files\Analog Devices\VisualDSP 5.0\214xx\Examples\ADSP-21469 EZ-Board

The example code "Talkthrough_IIR_Accelerator" is a realtime example that uses IIR accelerator to process the audio data from the codec and send it back to the codec. It can also be modified for using FIR accelerator.

You might also want to have a look at the Expert Code Generator - VisualDSP plugin and few associated example codes for FIR/IIR/FFT accelerators with EE-322 at link below:

Hope this helps.

Thanks,

HI Michael,

I am also having update 7 here. Not sure what's the problem. I shall  install update 7 freshly from the link below

http://www.analog.com/en/embedded-processing-dsp/software-and-reference-designs/content/visualdsp_tools_upgrades/fca.html

and check whether I see those examples here again.

I am also attaching the example codes I was referring to with this post.

Hope this helps.

Thanks,

Mitesh

Thats what I thought the stuff should be -- but my ....Program

Files\Analog Devices\VisualDSP 5.0\214xx\Examples\ADSP-21469 EZ-Board 

directory does not have that file

Is there a VDSP update I am missing -- Have 7

Hi Michael,
