Month: 2025-08 — Key focus: ARMv7 NEON intra predictor stability and NEON optimization in aom. Key actions: fixed SIGBUS by switching buffer loading from load_u8_4x1 to load_unaligned_u8_4x1; enabled NEON-optimized intra predictor; re-enabled av1_filter_intra_predictor_neon for Armv7. Impact: robust intra prediction on Armv7, reduced crashes, improved encoding/decoding performance, broader device support. Technologies: Arm NEON, unaligned loads, AV1 intra predictor, C/C++, aom.

January 2025 monthly summary for repository madeline-underwood/arm-learning-paths. Focused on improving developer clarity around SVE vector length configuration and aligning documentation with code usage. Delivered a targeted documentation update to sve_armie.md to specify that vector length is defined in bytes (not bits) and updated the example command to use 32 for a 256-bit vector. This reduces misconfiguration risk and supports correct API usage by downstream consumers.

Month 2024-11 focused on stabilizing ARM build workflow and preventing build-time issues in the aom library. Delivered a critical typo fix in CPU CMake that ensures correct ARM build flags references, improving cross-target reliability and reducing potential CI failures.
