A high-speed image acquisition system for USB2.0

High-speed image capture technology is widely used in image signal transmission, processing, pattern recognition and industrial control. LVDS signal transmission technology and Hotlink transmission technology are two kinds of image signal transmission method who has been widely used in different areas because its own strengths. Because of its high-speed and strong interference immunity, LVDS signals have became the ideal choice in industrial on-site for high-speed signal long-term transmission. Hotlink, a new generation interface for point to point high-speed serial signal transmission, is gradually being accepted by the users because of the promotion of Cypress. FPGA, field programmable gate array, is used as the core of the design PCB for its low cost, flexible. We take advantage of their strengths, use FPGA collect the signal from LVDS interface or Hotlink interface, and translate the signal into the form that meets the USB protocol, then translate the image data to the computer throw USB interface.
