Yeah, my toolchain is more or less the same as Anima's, I just chose Qt Creator instead of Eclipse, the rest (Vincent's cross tools, DSP binaries for Windows by Motorola) is the same.
Cute56 (https://github.com/mikrosk/cute56) is a lame attempt to make a nice simulator/debugger with UI but honestly, using Hatari + its DSP debugger may make more sense these days. But it has its learning curve. ;)
When it comes to the DSP itself, the best you can do is to start playing with its instructions -- see how MPY(R) / MAC(R) work, try parallel moves, create a simple transformation matrix... At the end of the day it's quite easy, really (it's a RISC after all), the real challenge is to cope with lack of memory and slow CPU <-> DSP channel.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
