Month: 2026-01 — Libsdl-org/aom feature delivered: HighBD SAD Neon optimization. Increased SAD accumulators in the highbd_sad Neon path from 2 to 4 to boost parallelism for selected block sizes and added a separate implementation for 16-wide SADs, preserving the 2-accumulator path for standard sizes. Commit 242f885743f2c7957679c5ede8bef7d242b2124c; Change-Id: Iabd0aba59ad532cfffa8157a00f3c02552cd1f29. Impact: improved Neon-based high-bit-depth SAD performance, reduced per-block compute, and better throughput on Neon-enabled devices. No major bugs fixed this month. Technologies/skills: Neon SIMD optimization, high-bit-depth video processing, code review traceability, and commit-based traceability.

November 2025 - Libsdl-org/aom: Delivered a high-bit-depth convolution performance optimization for highbd_convolve8_vert_8tap_sve on Arm. Key changes reduced block size to 4x4, replaced TBL2-based shuffling with transpose_concat (ZIP1/2), and removed costly lookup table index setup. Result: faster high-bit-depth convolution, improved encoder/decoder throughput on Arm, and a foundation for further performance work. No major bugs fixed this month; stability and code quality improvements were maintained.

October 2025 monthly summary for libsdl-org/aom focusing on performance optimization in the high-bit-depth convolution path. Delivered targeted improvements to the highbd_convolve_y_sr_12tap_sve2 function on Arm SVE2, emphasizing data layout and block processing to boost runtime efficiency. The work enhances throughput for high-bitrate video paths and establishes a foundation for broader platform performance gains.
