Subject: [FFmpeg-devel] [PATCH 0/5] Provide neon implementation for me_cmp functions
Date: Tue, 16 Aug 2022 14:20:11 +0200
Message-ID: <20220816122016.64929-1-hum@semihalf.com> (raw)
Add arm64 neon implementation for functions from motion estimation
family. All of them were tested and benchmarked using checkasm tool.
The rare code paths, e.g. when filter_size % 4 != 0 were also tested.
Instructions were manualy deinterleaved to reach best performance.
Hubert Mazur (5):
lavc/aarch64: Add neon implementation for sse16
lavc/aarch64: Add neon implementation for sse4
lavc/aarch64: Add neon implementation for pix_abs16_y2
lavc/aarch64: Add neon implementation for sse8
lavc/aarch64: Add neon implementation for pix_abs8
