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

本程序是MP3的解码程序，可以用VC编译或者用GNU编译，可以运行在PC机上。 本程可以MP3文件解压为WAV文件 TEST 中的代码可以播放WAV文件 有兴趣的朋友可以把这段mp3程序移植到开发板上，这样就可以用开发板播放MP3了-MP3 decoding procedures that can be used with VC or GNU compiler compiler. can run on the PC. The process can decompress MP3 to WAV TEST document of the code can be broadcast WAV documents are interested friends this can be transplanted to mp3 development board, we can develop with the board to broadcast MP3
