Subject: [FFmpeg-devel] [PATCH] lavc/aarch64: Add pix_abs16_x2 neon implementation
Date: Tue, 12 Jul 2022 11:15:32 +0200
Message-ID: <20220712091533.429382-1-hum@semihalf.com> (raw)
In-Reply-To: <20220629082440.119841-3-hum@semihalf.com>
Thanks for the feedback. I made changes to the patch.
The performance has increased now to ~7 boost compared
to C implementation.
Changes:
- Do not use v8-v15 registers.
- Use urhadd instruction.
- Reorder the instructions to increase performance.
// Hubert
