Die Entwickler des Projekts FFmpeg haben neue Optimierungen durch Assembler angek\u00fcndigt, bei denen die Verwendung des AVX-512-Befehlssatzes zur Beschleunigung bestimmter Operationen beim Dekodieren von Videos f\u00fchrte. Die Leistungssteigerung des Assemblercodes mit AVX-512-Befehlen betrug das 94-, 44-, 64- und 4,24-fache im Vergleich zur Basisimplementierung, die in C ohne Verwendung von SIMD-Befehlen geschrieben wurde. Im Assemblercode mit AVX-2-Optimerungen betrug die Steigerung das 67-, 27-, 55- und 4,38-fache, w\u00e4hrend die Optimierungen auf SSSE3-Basis eine Steigerung von 40-, 21-, 29- und 2,49-fachem bewirkten. Die \u00c4nderungen wurden in die Bibliothek dav1d aufgenommen, die einen alternativen Dekodierer f\u00fcr das AV1-Videoformat anbietet. Die AVX-512-Befehle sind in AMD-Prozessoren auf Basis der Mikroarchitekturen Zen 4 und 5 sowie in Intel-Prozessoren mit Mikroarchitekturen wie Skylake-X, Ice Lake, Tiger Lake und Rocket Lake verf\u00fcgbar.
