A high-definition video display system for medical endoscope based on SoC

Objective To develop a high-definition video display system for medical endoscope based on system on chip (SoC),and meet the requirement of high-resolution and real-time video display.Method A CMOS camera was used for video data capture.A SoC chip,integrated with a dual-core ARM Crotex-A9 processor and a field programmable gate array (FPGA),was employed as the kernel of the system.The HPS part of the SoC was used to build an embedded system to realize human-computer interaction,and the FPGA part was used to store and cache video data.The HPS and FPGA part were connected through a high-performance ARM AMBA AXI bus bridge broadband system,so as to achieve encoding of the cached video data and real-time display on screen.Results A high-definition video display system was built based on SoC.This system can achieve capture,processing and realtime display of high-definition video,as well as video freeze function.Conclusions The experimental results indicate that this system is feasible and effective,and possesses the advantages of customizability,multiple-exploitation and high performance of real-time video display.
