Digital image processing consume a large amount of memory and time commonly. basing on the advantage of fpga, the paper design harware module by hdl ( hardware language ), i. e., some function is achieved by les ( logic element ) of the fpga. the real - time of digital image processing is achieved by this. the sample and display of digital image is the important part. so, the paper mainly design the sample and desplay module. the sample card is designed and it ’ s word mode is configured according china ’ s cvbs ( composite video bar signal ). for acquiring the image and storing it correctly to sram, the paper design the sample - control module. the sample module can work correctly using least time. the reliability and real - time achieve the reference. according the vga principle and scheduling of the ths8134, the paper design a vga - control module by hdl. firstly, the control signal is synthesized secondly, the horirontal and vertical synchronization signals is synthesized according to the vga interface standard
圖像處理的特點是處理的數據量大，處理非常耗時，為實現數字圖像的實時處理，本文研究了在fpga上用硬體描述語言實現功能模塊的方法，通過功能模塊的硬體化，解決了視頻圖像處理的速度問題。圖像數據的正確採集和顯示輸出是其中的兩個重要的模塊，因此，本文主要完成了圖像數據的採集和顯示輸出的設計。本文設計了採集卡，並要對其工作模式進行了配置和編寫了採集控制模塊，在採集控制模塊的控制下，將數字圖像數據正確無誤的存儲到了sram中。 -
