Abstract: The image compression system based on FPGA+DSP architecture is introduced, and its system structure, principle and implementation are described. The system uses FPGA+DSP architecture to establish a high-performance image real-time compression device. The terms of system hardware, software and mechanical structure are optimized design, the functions of the multi-channel video image capture, compression, transmission, and time series conversion are realized to meet the flight test environmental conditions. The system has the advantages of small delay, low power consumption, good environment adaptability. The system passed some environmental test including high and low temperature test, vibration and shock test, electromagnetic compatibility test, and has a high application value.
