PROFILE
Swami, Preksha
Worked on the google/XNNPACK repository to expand low-precision activation support by implementing PReLU microkernels for QS8 and QU8 data types, targeting both AVX2 and scalar instruction sets. Leveraged C and assembly programming to deliver new microkernel sources, update build scripts, and develop comprehensive tests, thereby improving performance and correctness for quantized inference workloads. Later, refactored the quantized ReLU path to remove unused variables and streamline code across AVX2 and scalar paths, enhancing maintainability and potentially reducing binary size. The work focused on low-level optimization, performance optimization, and SIMD programming to support efficient, reliable quantized model inference.
