In order to solve the problem that the data output of space optical remote sensing imaging system is multi-channel and high rate

a new design scheme for high-speed and multi-channel CCD (Charge Coupled Device) image data parallel processing and transmission system is proposed. The design uses field programmable gate arrays (FPGA) for the data processing and logic control. For high speed and multi-channel CCD image data processing

the paper adopts regional parallel processing based on FPGA. The FPGA inner block RAM is used to build high speed image data buffer and time-division multiplexing is put into operation to achieve high speed multi-channel image data integration and real-time processing. For high-speed multi-channel CCD image data transmission question involved

the paper analyzes in-depth low-voltage differential signal and high speed differential serial transmission technology

and put it in practice. Those technologies enhance the system high-speed transmission capacity

and lower power consumption

strengthen anti-interference ability. The result shows that the design has good stability

flexibility and versatility

which has already been successfully used in a 40-channels high-speed CCD imaging system with the data rate up to 7.68 Gbit/s.
