Abstract—The integration of high-resolution imaging in modern medical diagnostic devices demands a robust, efficient, and standardized data interface between image sensors and processing units. The Mobile Industry Processor Interface (MIPI) Camera Serial Interface 2 (CSI-2) protocol, originally developed for mobile and embedded applications, is increasingly being adopted in medical imaging systems due to its high-speed, low-power, and scalable communication capabilities. This work presents the design and implementation of the MIPI CSI-2 protocol tailored for medical imaging applications, focusing on reliable transmission of real-time image data from high- resolution sensors to processing units. The proposed design covers the protocol's layered architecture, including packet formatting, virtual channel utilization, error handling, and flow control mechanisms. Implemented using System Verilog, the design is verified using simulation and synthesis tools, ensuring accurate data transmission over the MIPI D-PHY physical layer. Emphasis is placed on low latency, deterministic performance, and minimal power consumption - critical factors in medical environments where precision and reliability are paramount. The CSI-2 protocol's flexibility enables integration into various medical imaging modalities, enhancing data fidelity and system responsiveness. This work lays the groundwork for the adoption of standardized, high-efficiency interfaces in next-generation medical imaging devices.
