Worked on the Xilinx/mlir-aie repository, delivering advanced AI and ML acceleration features for AIE hardware. Over seven months, developed and optimized multi-core kernels such as RMSNorm, ROPE, LayerNorm, and softmax, while enhancing vector reduction and memory management capabilities. Applied C++, Python, and MLIR to refactor compiler interfaces, centralize coordinate logic, and improve buffer allocation robustness. Addressed build reliability, CI stability, and documentation to streamline onboarding and reproducibility. Focused on maintainable, test-driven development, the work improved normalization performance, transformer support, and error handling, enabling scalable, high-performance ML pipelines on embedded and FPGA-based systems with robust code quality.

Jul 1, 2025July 2025 monthly summary for Xilinx/mlir-aie focusing on deliverables, quality improvements, and impact. Key features delivered: - Vector Reduce Max improvements: single-column designs with INT32 and BF16 data types, generic reduction logic, and multiple reduction strategies (cascade, shared memory, memory tile aggregation). Updated build configurations and test benches to accommodate new designs and data types; introduced unplaced designs for multi-column and single-column reduction strategies with related build script and Makefile/Python refactorings. Major bugs fixed: - AIE dialect buffer allocation robustness: fixed unhandled errors during buffer allocation, refactored error handling to return bool, and emitted warnings for specific allocation failures to ensure proper fallback strategies. Overall impact and accomplishments: - Strengthened vector reduction capabilities and data-type support, improving performance paths and design flexibility. - Increased build/test reliability and maintainability through script and test bench updates and refactors. - Reduced risk of allocation-related failures in the AIE dialect, enabling more robust runtime behavior. Technologies/skills demonstrated: - MLIR-based design, C++, build systems (Makefile, Python scripts), MLIR AIE dialect, debugging and error handling, and test-driven development.
