Worked on performance-oriented enhancements for the libsdl-org/aom repository, focusing on optimizing core data paths within the aom library. Leveraged C and low-level programming skills to refactor warped motion filtering, reducing the filter coefficient data type from 16-bit to 8-bit in generic code paths, which improved compiler vectorization and lowered memory bandwidth usage. Additionally, restructured variance calculation logic to utilize local variables for sum and SSE, enabling better vectorization potential while maintaining existing functionality. The work emphasized compiler optimization and vectorization, laying the groundwork for future cross-architecture SIMD improvements on both ARM and x86 platforms without introducing new bugs.
