PROFILE
Salome Thirot
Salome Thirot developed and optimized ARM NEON-accelerated features for the libsdl-org/aom repository, focusing on AV1 video codec performance. She engineered SIMD and low-level optimizations in C and assembly, targeting loop filter and prediction paths to enhance encoding and decoding speed on ARM devices. Her work included refactoring NEON implementations for code reuse, introducing early exits, and optimizing memory access, while porting techniques from SVT-AV1 to align with industry best practices. Salome also simplified AArch64 SIMD logic for svt_compute_stats_win5_* step3, improving throughput and maintainability. Her contributions demonstrated deep expertise in performance-driven, maintainable video encoding solutions.

Jan 1, 2025Month 2025-01 summary for libsdl-org/aom: Delivered performance-focused ARM NEON optimizations for AV1, spanning loop filter and prediction paths. Implemented NEON improvements for aom_lpf_6/8/14, aom_lpf4, high-bit-depth variants, and cfl_predict_neon, with refactoring to improve code reuse, early exits, and optimized memory access. Ported and adapted optimization techniques from SVT-AV1 to accelerate ARM performance. No major bug fixes were recorded this month. Overall impact: enhanced encoding/decoding performance on ARM devices, enabling faster mobile/embedded media processing and potential energy efficiency gains. Improved maintainability through targeted refactoring and clearer performance characteristics. Technologies/skills demonstrated: ARM NEON intrinsics, SIMD optimization, cross-repo knowledge transfer (SVT-AV1), performance-driven development, and code refactoring for maintainability.
