PROFILE
Ryan Antonio
Worked extensively on the KULeuven-MICAS/snax_cluster repository, delivering hardware-software features for accelerator integration, data processing, and recognition workloads. Developed multi-accelerator support for RISC-V cores, optimized DMA transfers for high-dimensional data, and implemented robust CI/CD workflows to ensure reproducible builds. Enhanced the Hypercorex library and recognition pipelines by refining configuration parameters and data interfaces, while expanding test infrastructure and documentation to improve onboarding and validation. Utilized SystemVerilog, C, and Python scripting to build and validate hardware modules, automate data generation, and streamline build systems. Focused on maintainability, performance optimization, and scalable hardware design throughout the development cycle.

Aug 1, 2025Month: 2025-08 - Delivered extended support for longer tiled programs across multiple applications in KULeuven-MICAS/snax_cluster, enabling processing of larger/more complex data patterns across digit, DNA, language, and UCIHAR. Implemented end-to-end changes including new 'long' variants, build-system updates, and data generation tooling, with targeted C source modifications to accommodate extended functionality. This work reduces future integration effort and enables broader applicability of the clustering/HD C workflow while maintaining stability and testability. No major bug regressions observed; groundwork laid for performance tuning and scalability.
