[x265] [PATCH 00/12] AArch64: Optimise low bitdepth ipfilter primitives

[chen]

Hi Hari,




Thank for the patches, I have no comment on this initialize version.

In future version, we may improve by algorithm.

For example, width=12 may split into 2 of witdh=8, it got cache benefits.




Regards,
Chen
