> architectures that don't support NEON (they often lack them in Marvell and Allwinner).
I'm probably nitpicking here, but:
* All Allwinner SoCs have NEON[0]
* Most current ARMv7 processors have NEON. Of the current ARM cores, only Cortex-A5 and Cortex-A9 don't have mandatory NEON support (it's optional). Cortex-A5 is intended for embedded applications. Of the existing Cortex-A9 processors, AFAIK the only somewhat popular one without NEON support is NVIDIA Tegra 2, which is retired. Out of the third party cores, all Qualcomm and Apple ones have NEON support.
Yes, and as jmpe said they have quite a few SoCs without NEON (I think basically everything apart from ARMADA 1500 plus). They seem to be targeting devices like smart TVs and STBs nowadays, so I guess it's not a big deal.
Correct, it was wrong of me to point to "architectures" that lack Neon; you're correct in your reply. I should have mentioned specific implementations. My experience with Allwinners without Neon indeed comes from smart TVs and STB. You know your stuff ;)
