Hi,
I asked some things about NEON in another thread (http://forum.xbmc.org/showthread.php?tid...pid1166442), but I have not received any answer yet.
I would like to understand how NEON is working. Is it for accelerating all kinds of codecs? Strong enough for decoding h264 1080p videos? e.g. in a 1Ghz arm cpu? or is it for something else?
Thanks in advance
NEON is a vector math processor, like mmx or sse in x86 world. It does nothing by itself, you have to write code to use it.
