S. Vivekan developed and enhanced floating-point and integer conversion features in the riscv-software-src/riscv-unified-db repository, focusing on RISC-V instruction set architecture and embedded systems. Over six months, Vivekan implemented core arithmetic operations such as fadd, fsub, and fround, integrating robust rounding logic and edge-case handling for single-precision floating-point numbers. Using IDL and YAML, Vivekan clarified language semantics, improved documentation, and refactored code to support accurate symbolic analysis and downstream toolchain interoperability. The work addressed both feature delivery and bug resolution, resulting in more reliable simulations, improved data fidelity, and maintainable code for RISC-V numerical processing workflows.
