Not so much a resource, but it's fun to play around with...

Cheers,

hope to see more on this, looks promising. a homebrew development platform for the Wavefront DSP's

Oh, and if anyone else is brave enough to tackle the Axoris Miss Parker project: I found a source for the obsolete Cypress AN2135sc USB Microcontroller. German site, good service.

A nice book that can be downloaded as PDF-files: http://www.dspguide.com (http://www.dspguide.com)
It's not audio oriented, but the stuff can be aplied to audio stuff too. I haven't read it through yet (I'm somewhere around chapter 10), but it seems quite nice. It explains the basic concepts so that they are quite easy to understand.
On the Analog Devices website, there are a lot of articles. http://www.analog.com/ (http://www.analog.com/) It's a bit hard to find what is interesting because there are a lot of articles, it's such a mess!
There is this article based on the ADSP21065L for example:

And there are the asm files described in the article:

These links are broken, but I could find one of them somewhere else:
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.110.4688&rep=rep1&type=pdf (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.110.4688&rep=rep1&type=pdf)
It contains useful examples of typical effects coding (chorus, delay, filters, etc...)
Any good info on Xillinx chips? I know the IDE is expensive, I think.
had a look at the wavefront products, but it looks like they are disappearing off the market. Shame, they look pretty good...

Here I add DAFX conference proceedings, for almost all years from 1998 to 2021. Thousands pages of papers containing all about digital audio effects, most all of them is free to download. Here is the link: https://www.dafx.de/
Scott Dattalo archives (https://web.archive.org/web/20120225045334/http://www.dattalo.com/technical/software/software.php)
The implicit link breaks at the second "//".
I had to wrap URL tags around it to make it clickable.

Thank you! It should be fixed now.
