PROFILE

Henry Hsieh

Worked on the riscv-unified-db repository to enhance correctness and specification compliance in RISC-V ISA decoding, focusing on the I, Zicbop, V, and C extensions. Addressed a critical bug by implementing sign-extension fixes for immediate values, ensuring accurate decoding and reducing the risk of regressions in simulations and tooling. The approach emphasized clean, traceable commits with thorough documentation and references to related issues for future maintainability. Utilized skills in ISA design, RISC-V architecture, and low-level programming, with changes implemented in YAML and hardware description languages to align decoding logic with the official RISC-V specification and improve reliability.
