随着计算机技术应用范围的不断扩展,人们要求计算机不仅仅有高分辩率的显示效果,而且还要有类似示波器的动态显示效果,这种技术配合A/D转换器的工作,便可构成一台数字示波器。这种技术的应用场合十分广泛,本文结合TVGA8900系列适配器的结构,对这种技术给出较为详细的阐述。 1.TVGA工作模式简介 Trident公司近年来推出的TVGA8900卡是一种通用的功能强大的显示控制卡,它与IBM标准的VGA卡相比较有更多的优越性。它能支持的分辨率为1024(X)＊768(Y)＊256(色)的图形模式(62H)和分辨率为1024(X)＊768(Y)＊16(色)的图形模式(5FH),前者是每页128K
With the continuous expansion of the application of computer technology, people require computers not only have high-resolution display, but also have similar dynamic display oscilloscope, this technology with the work of A / D converter, can form a Digital oscilloscope. The application of this technology is very extensive, this article combined TVGA8900 series adapter structure, this technology is given in more detail. 1.TVGA mode of work Brief introduction Trident TVGA8900 card introduced in recent years is a versatile and powerful display control card, which is compared with the IBM standard VGA card has more advantages. It supports graphic modes with a resolution of 1024 (X) * 768 (Y) * 256 (62H) and a graphics mode with a resolution of 1024 (X) * 768 (Y) * 16 ), The former is 128K per page
