PROFILE
Wang Yi Jie
Worked on the riscv-software-src/riscv-unified-db repository to enhance the correctness of bit-manipulation operations within the RISC-V architecture. Focused on aligning the andn instruction with the Bit-Manipulation Extension specification by correcting operand order, ensuring that X[xs1] & ~X[xs2] is computed as intended. This change addressed spec compliance issues and improved the reliability of downstream tooling that depends on accurate bitwise operations. Collaborated with peers, as reflected in co-authored commits, and utilized skills in hardware description languages, low-level programming, and YAML. The work reduced the risk of specification violations and contributed to a more robust RISC-V bit-manipulation feature set.
