Abstract

This paper presents the design and implementation of a custom 32-bit RISC-V processor with a 5-stage pipeline architecture deployed on a Xilinx Spartan-3A FPGA. The processor is designed to control and automate home appliances through a flexible and open-source hardware architecture. The use of the RISC-V instruction set provides scalability, customizability, and cost efficiency compared to proprietary microcontrollers. The FPGA platform enables real-time performance with parallel hardware execution and easy reconfiguration. The proposed system successfully demonstrates real-time control of household devices such as lighting, fans, and sensors. Experimental evaluation shows that the processor achieves stable operation with acceptable timing performance and moderate FPGA resource utilization, making it a suitable candidate for low-cost and energy-efficient smart home systems.
