Innovative RISC-V Processor Implementation with Nand Gate Standard Libraries for Low-Power Computing

Abstract

This paper presents an innovative design of a RISC-V processor architecture utilizing a specialized library of NAND gate standard cells. The primary objective is to achieve a compact, energy-efficient, and high-performance computing system by optimizing the fundamental logic gates within the processor core. By focusing on a NAND-based standard library approach, the design enables streamlined logic synthesis, reduced leakage power, and improved area efficiency across the silicon floorplan. The processor architecture is meticulously optimized to leverage the logic density of NAND-based cells, ensuring high-speed switching and minimized power-delay products while maintaining structural integrity. Detailed simulations and performance analyses demonstrate significant reductions in dynamic power consumption compared to generalized CMOS designs, without compromising the computational throughput required for modern applications. This proposed approach provides a scalable and robust solution for next-generation embedded systems. The entire architecture is designed and verified in the Xilinx Vivado software environment using Verilog HDL.
