Medical Endoscope RK3568 ARM+FPGA Solution

Medical Endoscope

Endoscopes are inserted into the human body through natural orifices or small surgical incisions. When in use, the endoscope is guided into the organ to be examined, allowing direct visualization of changes in the relevant areas. The quality of the image directly impacts the effectiveness of the endoscope and signifies the level of development in endoscope technology.

A certain company leverages the domestically produced RK3568 core board to support high-end localized medical imaging instruments. With deep customization of kernel drivers, it has overcome USB signal transmission attenuation, achieving stable and clear image quality, dual-screen mirrored/extended display, and adaptability to multiple scenarios, leading to its widespread adoption.

RK3568 Core Board

1. Clock speed 2GHz, 2GB RAM, 8GB ROM
2. HDMI and local LVDS screen, dual-screen mirrored/extended display
3. Support for long-handle endoscope lens debugging, stable transmission
4. Panasonic board-to-board connectors, precise and reliable
5. Linux operating system, customized system optimization

Introduction to FSPI and PCIe Buses

FSPI (Flexible Serial Peripheral Interface) is a high-speed, full-duplex, synchronous serial communication bus. The RK3568J processor includes an FSPI controller, which can be used to connect FSPI devices. It has the following features:

(1) Supports serial NOR FLASH and serial NAND FLASH;

(2) Supports SDR mode;

(3) Supports single-wire, dual-wire, and quad-wire modes.
