Just a note if you're wanting to do real time processing I doubt that a uController would be able to sample at a very fast rate as most are limited to 20MHz. Additionally uControllers do not have a FPU so all calculations would be done in firmware which is slow.
Just thought I'd throw my 2 sense in.

I did a quick read on discrete wavelet transform in Wikipedia, and he may not be that far off base. A DSP implementation seems obvious as well.

It can and has been done but the sampling rate for a typical uController would be low due to the factors I mentioned.

Agreed, but the math looks like a natural for a number of fixed-point arithmetic techniques. As always, it depends on the problem you're trying to solve.

True and after posting did some digging in an Atmel uController instruction set reference and found some instructions that deal with fractional data that are ideal for signal processing. So I only shot off 2 toes instead of the whole foot.

I feel lucky then that only two toes took the hit.

Microchip provides a family of microcontrollers dedicated to DSP (see dsPIC30F[^] and dsPIC33F/E[^]).
Veni, vidi, vici.

Thanks not familiar with the PIC line of uControllers, have only worked with the 8-bit line of Atmel uCOntrollers so I guess I mistakenly assumed the OP was thinking along the same lines. My bad!

It can be done, but the wavelet has to want to transform.

Haven't heard that one in a while. Is one of those albums I remember listing to a long time ago. Haven't heard the album since that time. Thanks
It was broke, so I fixed it.

I actually bought it on tape - had a JVC 'walkman' kind of thing, a bit larger than Sonys product ... and it was my favourite for the rest of that summer ...

I'd look at OpenBSD. I used it once as a transparent firewall. Didn't have any hacks that I know of, so I assume it worked.

The Red Hat 7.1 I have (from 2001) seems to require a minimum of 32MB and a 486. Does your system have a 3.5" floppy drive?
