Is there a good reference for ARM Neon intrinsics?

Question

The ARM reference manual doesn't go into too much detail into the individual instructions ( http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0348b/BABIIBBG.html ). Is there something that's a little more detailed?

Solution 1

For more information on the instructions themselves, you need the Assembler Guide. The list you found there just shows the mapping from compiler intrinsics to assembly instructions.

Solution 2

There's also the ARM C Language Extensions which provides details on the usage of the intrinsics (see chapter 12) that could be useful.

Solution 3

There is now an HTML version of the NEON Intrinsics Reference which is pretty convenient. Each entry includes a link to a more detailed explanation of the relevant instruction.

It's still not quite as good as Intel's, which lets you filter by instruction set and includes pseudo-code implementations, but it's a huge improvement over the old PDFs.

As of yesterday, I started to write this (contributions welcome): github.com/thenifty/neon-guide

The linked page is marked to be superseded, any idea where the updated version can be found? Maybe this?

@Antonion, your new link also superseded, nowadays. An update: infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0473‌​m/…
