C5515 HWAFFT Runtime Environment


I'm working with C5515 eZdsp. I'd like to try hwafft function in order to transform a signal coming from with I2S codec using Pingpong buffer DMA.

The signal is sampled correctly, but i need to know where to find hwafft environment and how to include it in my project.

I googled around for documentation, and found this document: http://www.ti.com/lit/an/sprabb6b/sprabb6b.pdf, but no files to include in my project at all...

Any tips?

Thanks in advance
