基于SOPC图像采集系统的设计

Design of Image Acquisition System Based on SOPC

提出一种基于SOPC技术的图像采集系统的解决方案。该采集系统通过在单片FPGA上配置采集控制电路和USB2.0通信控制电路,可以实时传输外界图像数据。以图像传感器OV7660为图像采集芯片,EP2C8Q208C8为主控芯片,USB2.0芯片CY7C68013为通信芯片,设计了一个图像采集与传输系统。该系统具有体积小、功耗低、设计灵活、可扩展性好等特点。

A solution of image acquisition system based on SOPC technology was presented.The acquisition system is capable of capturing image information from the scene in real time via the acquisition control circuit and USB2.0 communication control circuit implemented on one FPGA.A system of image acquisition and transmission was developed on the basis of Cypress Corporation＇s high speed USB peripheral controller CY7C68013,Altera Corporation＇s EP2C8Q208C8 and OmniVision Corporation＇s CMOS image sensor OV7660.The proposed acquisition system has the characteristics of small size and low power dissipation,as well as high design flexibility and expansibility.
