提出一种采用FPGA内置RAM存放字符点阵库实现动态字符显示的新的设计方案,该方案只需要将待显示字符的码值写入FPGA内部RAM中,FPGA程序就能实现对这些字符的实时显示。文章还介绍一种应用该技术的典型的数字图像处理系统,字符显示由FPGA完成,为处理器腾出更多的时间用于算法运算,从而提高了系统的性能。
This paper presents a new way of realizing real time dynamic character matrix library and character indexes. The paper also describes a typical digital technology. Character display is done by the FPGA, which saves time for processor to the performance of the whole system. display using RAM in FPGA to store dot image processing system applying the complete arithmetic and finally improves the performance of the whole system.
