一种布尔变换及解变换方法在数据处理中的应用

USING TRANSFORMATION AND INVERSE TRANSFORMATION OF BOOLEAN ALGEBRA FOR DISPLAY DATA PROCESSING

通常情况下，由于计算机在字符显示状态下在内存中存在一个显示代码缓存区，此缓存区存放屏幕上显示内容的ＡＳＣⅡ码；因此在ＬＥＤ显示应用上，尤其在需要将控制机显示内容在另一区域的ＬＥＤ屏幕重现时所需要的数据传输方面上，上述代码缓存区具有重要的作用．但是当我们使用象ｐｃ－１５００这样的机器作ＬＥＤ显示系统的控制机时，由于它无上述的系统有规律的顺序显示代码缓存区，同时鉴于ＬＥＤ与主控机点阵的不同及需传送的数据量等问题，我们在传输屏幕内容上存在一定的困难．本文提出并采用一种布尔变换及解变换方法来解决这个问题．

Generally, the computer display code buffer memory is served to store the ASC Ⅱ codes of the information which would be appeared on the screen of the computer in cha racier method. And the character generator convert ASC Ⅱ codes which are put out from display code buffer memory to character dot matrice and display them on the appointed location of the screen while the display output is running. In the LEDs display application, the display code buffer memory is essential for us to realize the data transmission, which perform what brings the display information into correspondence with that of the remote subsystem of LEDs display panel simultaneously. While we utilize pc-1500 as the control computer, as its irregular display code buffer memory and the difference of dot matrix between the LEDs panel and control computer screen, so we have some problems in the job. This paper gives a method of Boolean transformation and inverse transformation for us to solve them,and the performance of the new method is very well.
