PROFILE

Charles Jenkins

Charles Jenkins focused on backend development and embedded systems during his work on the riscv-unified-db repository, addressing a critical bug in immediate sign-extension handling for branch and jump instructions. He implemented correct sign extension for BGEU, BLTU, and JALR instructions by updating YAML definitions and enabling sign_extend behavior, ensuring proper treatment of signed immediate values in the instruction set. Using hardware description languages and configuration formats like ADOC and YAML, Charles validated the changes through targeted verification and code review. His work restored correct branch and jump behavior, improving downstream tool reliability and maintaining data-model consistency across the project.
