Using FFT accelelator in

Question asked by imu on Feb 5, 2015

Hi,

 

I am currently using the ADSP21489 EZ Kit to run the example:

 

\214xx\Examples\ADSP-21489 EZ-Board\21489 AD1939 C Block-Based Talkthru 48 or 96 kHz

 

The above example basically takes NUM_SAMPLES (=256) audio from ADC and copies them to DAC to analog outputs.

 

In this audio I/O routing example, I would like to integerate the FFT accelarator example:

 

\214xx\Examples\ADSP-21489 EZ-Board\256pointFFT

 

Meaning, I would like to perform FFT and IFFT of the incoming samples before copying them to the output buffer in the: 21489 AD1939 C Block-Based Talkthru 48 or 96 kHz

 

Is this possible to do this? If yes, how can I add the FFT/IFFT accelerator to the block-based routing example? Please advice!

Thanks
