[Abstract]:In order to solve the problem that it is not easy to transmit large quantities of data in high speed transmission system, a design method based on chip system image compression card is proposed. The configuration mode of soft core Nios II processor is discussed, which simplifies the hardware implementation principle of SPIHT algorithm and the operation flow of LVDS image data receiving and transferring. The design principle and implementation method of each module of the system are discussed in detail, and the actual performance of each module is tested and analyzed. The results show that the compression card has stable performance and can effectively complete image data compression.
