Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S

在pc 机的根目录下建立minigui- free 目录，将下载的源代码包copy 到该目录， 解压缩，生成libminigui-1.3.3、minigui-res-1.3.3、mde-1.3.0、mg-samples-1.3.1。 我在该目录中建立nfsroot 目录，用以存放生成的文件。-Pc machine in the root directory of the establishment of minigui-free directory, will download the source code package to the catalog copy, extract, generate libminigui-1.3.3, minigui-res-1.3.3, mde-1.3.0, mg- samples-1.3.1. I create a directory in the nfsroot directory to store files generated.
