Chapter 34: Conclusion, What is to be Done?
Well that's it for the AArch64/ARM64 tutorial. I told you it wasn't going to be fun. Anyway, there was still quite a bit of content that we didn't cover. For starters, we only skimmed over the bare-bones basics of Exceptions and EL's. Be sure to read up more on that topic. We also did not go into detail about any of the various SPRs. There are 100's of them.
Why it may appear that we've dived pretty deep into the SIMD unit, we've really only scratched the surface. The SIMD unit is incredibly complex. Regarding the other instruction sets/modes, if you want to learn about the AArch32 mode, or the Thumb32 mode, you can find that information in an ARMv7 tutorial. There are plenty of those tutorials on the web.
The developer.arm.com website is best source to look up official information. You can search on ARM's website directly or just Google it with filtering for the ARM site (i.e. insert-desired-topic-here developer.arm.com).
Happy Coding!
