Audio Equalization

I'm currently a student and I am working on my thesis project. What I'm trying to do is use DSP for equalization in a guitar pickup. I'm new to DSP as it is not taught in my school. I'm looking for suggestion on which DSP would be right for this project. I've searched through the forums and found reference to the C5535 with the eZdsp development kit, and am considering using this one. Would this be a good choice?

    Hi there,

    The C5535 is tough to get into if you are completely new to DSP. I used it for my senior thesis and I was new to DSP as well, but it took 6 months of HARD WORK to get my project working. Although there are many resources for how to use the C55xx series, theres not a lot of resources for how to use the C5535 specifically, and theres a real lack of resources for beginners to DSP using the C5535. By real lack, I mean virtually nothing useful. Theres a C5515 training course (see some details here: http://processors.wiki.ti.com/index.php/Porting_C5000_Teaching_ROM_to_C5535_eZdsp) that can be ported to the C5535. It's not that helpful though, and not that easy to get running. I mostly had to teach everything to myself, for instance:
    What is a GEL file?
    What is a memory map, and what are the principles I need to know to make one?
    How do I debug my code?
    How do I set up peripherals (I2S, I2C, DMA, AIC3204, etc...) to work together to do parallel processing (which you will need to do if you want real-time processing)? 

    The answers to questions like this are scattered around various user guides, technical manuals, online articles on the WIKI, and forum posts for the C5535. It would be great if they were all consolidated in one user-friendly "How to user the C5535 for beginners" but there is no singular such resource.

    I don't mean to dissuade you. Yes you can do what you want to do with the C5535. It's just going to take a lot of work, and don't expect a LOT of help from TI, although moderators do selectively answer questions on the forums. Then there's people like me who will help if we can :)

    Good luck and hope this helped!!!!!
