Title: DSP library
Post by: vanjast on March 17, 2010, 10:11:20 PM
I've been reading/learning DSP, part time, for about 1-2 years, and am thinking that it might be usefull to start making a DSP library of sorts

I've done a lot of VB dsp stuff  :naughty: ... but am now busy (part time programmer) with a few big asm projects that require some heavy DSP calcs
I visualise/think that it would require the use of FPU lib (thanks Ray) or an optimised version thereof, and/or a fixed point maths version as well.

If anybody has any pointers (pun  :green2 ) it'll be great.

vanjast,
You are absolutely fearless.   
I developed an interest in DSP for Music applications about a year ago, and once I got into it, I realized that with my limited mental capabilities, I'd be researching it FOREVER, and, I'd probably never write any cool stuff.   
What exactly are you looking for?   
...Maybe, something like this: MATHEMATICS OF THE DISCREET FOURIER TRANSFORM

You are probably already aware of this one: DSP Central

If required, you may also want to have a look at the library of functions for complex number from:

Thanks

This is one of my first books... simple with programming examples.. http://www.dspguide.com/

I started reading up on this out of curiosity.. and the more the I read the more interesting it got.. Some sections would take 3x reading before I got it.
As time wore on I began to realise that DSP is 'simple maths application' of a seemingly complex subject, and that software can replace hardware (Xmos cpu's) adding flexibility to an application.

So ja.. I'm a middle aged kid discovering new toys..... :lol

ty for the link Vanjast, I also have an interest in DSP however hadnt really found an entry point when I first saw it some years back, looks like 2 great tutorials posted on this page :U
