Loop Unrolling in RISC-V

Loop unrolling significantly enhances performance in embedded systems, particularly in RISC-V architectures. By reducing loop overhead and increasing instruction-level parallelism, it minimizes control operations. However, this technique increases code size, necessitating careful consideration for systems with memory constraints.
