After benchmarking, i saw that the throughput of a NEON inst.is the same as a regular fp op. Should i care about NEON? @rygorous @cmuratori
@eee34353 @rygorous Is there some kind of cheat-sheet available that lists the various ARM impls and how their NEONs work, broadly?

@rygorous Or is this more of a "don't ask, don't tell" kind of situation? -
@cmuratori @eee34353 The latter. There's tons of ARM impls out there, half of them not designed or implemented by ARM Holdings. - Show replies

@cmuratori @eee34353@rygorous Apparently only for registered ARM developers. The publicly available doc is pretty sparse. :(Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori@rygorous "ARMv7A" isn't a CPU, it's an architecture. @eee34353 quotes having a Galaxy S3 Neo, Quad Cortex-A7. -
@cmuratori@rygorous @eee34353 Cortex-A7 is a little core, not built for high SIMD throughput. Includes it for software compatibility - Show replies
