针对航天光学遥感成像系统输出通道多、输出速率高的特点，提出一种高速、多通道CCD图像数据并行处理与传输系统的设计方案。该方案以FPGA为数据处理和控制核心，采用基于FPGA区域并行处理的数据处理方法，运用FPGA内部块RAM构建高速多通道CCD图像的缓冲区，在存取控制上采取区域缓存和时分复用的策略完成对高速多通道CCD图像数据的实时处理；而对高速多通道CCD图像数据的传输采用基于Channel link高速差分串行传输技术，以高速差分串行的LVDS(Low Voltage Differential Signal)数据流替代传统的并行“TTL/COMS”信号进行传输，使系统高速传输能力大大加强，并且功耗低，抗干扰能力强。研究结果表明，该设计具有较好的稳定性、灵活性和通用性等，并已成功运用于某40通道高速CCD成像系统中，系统并行处理和传输的总数据率高达7.68 Gbit/s。

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.
