There is an app note from ARM on this and I'm sure TI has reams of info available. I expect there are libraries available that already have optimized canned routines for various signal processing functions. When the CM4 was first out I attended a presentation which covered the DSP aspects. Seems they do fairly well with tight loops in FIR filters and such. -- Rick

Can u share resources, related to filters and transforms, having some good goog examples???

I expect others here can recommend some references. I believe someone here has written a well respected book on practical DSP. I can't recall who that was, maybe Rick Lyons or maybe Eric Jacobsen. I know I keep meaning to buy the book but it never hits me at a convenient point, lol. -- Rick

Rick's a frequent contributor to this group. I have his second edition. I need to get the latest. I did feel that the second edition was a bit scant on some of the absolute most basic concepts, but there aren't any other good self-study DSP books out there that I know of, and you can always ask for clarifications here (and I could be wrong -- I was approaching it as a guy who's been doing this stuff for decades, maybe I underestimate the audience). -- www.wescottdesign.com

I've always found it hard to get the concepts without some discussion and getting a few questions answered, preferably without math. I remember taking a class in DSP where the teacher was all about the math. The students kept asking "What does that mean?", expressing their lack of understanding on how to relate it to the real world. It's great to be able to push the equations around, but a "feel" is required to be able to apply this stuff easily. -- Rick

When I was learning all that stuff I was living 16 miles away from school and biking in four days a week. I'd pass the time on the road practicing making intuitive sense of the math. I'm enough of a math geek that I was willing to learn the stuff initially just because the math is pretty. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

I had to get to work to apply the stuff I was learning. -- Rick
