| Abstract: | A ping-pong buffer structure belonging to the hyperspectral imaging system is introduced which can effectively coordinate data transmission and processing speed by comparing with two other common ways of caching. The operation and control principle of ping-pong buffer structure is discussed. Based on the platform which consists of high-speed large-capacity SRAM and high-performance FPGA device，a ping-pong buffer structure to adapt to the hyperspectral imaging data transmission system is designed. Also the RTL simulation and the board-level verification are completed. Experiments show that this structure is efficient at seamless buffering and processing the real-time video data, and effectively improves the efficiency of the system，and proved to be stable and reliable. |
