This paper presents a compact FPGA-based controller for Reconfigurable Intelligent Surfaces (RIS) that integrates an embedded RISC-V processor and dedicated hardware control within a single device. The proposed architecture targets a 15×15 mechanical RIS prototype driven by stepper motor actuators. The embedded RISC-V processor accesses the RIS controller through a lightweight memory-mapped interface, enabling software-programmable RIS reconfiguration while fully abstracting low-level actuation details. By integrating processing and control within the same FPGA, the proposed platform eliminates the need for external computing units and reduces communication latency.
