Hi jay_

I'm not an expert on DSP, but recently I'm playing with it a bit, and trying to re-call the things I learned in college :-)

There is an example based on TMS320C6000 DSP:

http://www.ti.com/dsp/docs/litabsmultiplefilelist.tsp?sectionId=3&tabId=409&literatureNumber=spra867&docCategoryId=1&familyId=327

I'm trying to figure out how to migrate it into my C5535 eZdsp board.

Hope it helps.

Hi Wenbo.

Thank you for your answer.

I've found c5000 examples so you don't have to migrate c6000 lib.

Here is the link of the teaching lab.

http://www.ti.com/general/docs/gencontent.tsp?contentId=76582

and here is the wiki page to port with your board.

Hi Jay,

The C6000 example uses cascaded IIR filters to build an parametric equalizer, also, it provides a UI from PC side to control the "curve" of this equalizer.

The C5000 teaching lad provides single IIR filter, we need to figure out how to cascade them and perhaps also need to make a simple UI to control the "curve" in real time.
