Reference Material..

[TrashyMG]

So I guess now that we have a NEON/DSP section, where are some good guides for programming Neon or the DSP, such as tutorials and general useful info that would allow people to get started. If we can gather some good links I will put them here in this first post and pin the topic.

This is a list of TI C64+ DSP docs I posted on page 9 of the "announce" thread:

Some links are dead.
Is there any C NEON (no ASM) optimization tutorials ?

 

[ptitSeb]

This thread: https://pyra-handheld.com/boards/threads/neon-optimization.71710/ has some interesting info from notaz and exophase on how you should approoach NEON optim. There some example of NEON C optim with intrinsect too. I think that's the closest thing to a tutorial...

Cool, thanks !
