计算机输入设备输入的信息一般是由ASCII码或BCD码表示的数据或字符，CPU一般均用二进制数进行计算或用其他信息进行处理，处理的结果又必须依照外设的要求变为ASCII码、BCD码或七段显示码等。因此，在应用软件中，各类数制的转换和代码的转换是必不可少的-Computer input device input information is normally provided by ASCII code or BCD code that data or characters, CPU are ge

this a verilog code .. it converts 9 bit integer value to its corresponding twelve bit BCD number that is required as an input to a seven segment decoder or otherwise also an integer that may be represented by binary bits can be changed to its corres

七段LED数码显示器是数字系统中常用的数码显示元件，二进制数不能直接在LED数码管上显示，需要用一个BCD七段译码器进行译码。下图给出了一个七段显示译码器的框图及相应的七段LED数码管的示意图。-Seven-segment LED digital display is commonly used in digital systems digital display devices, a binary number can not be directly displayed on the LED
