Design a 4-digit BCD decimal counter module bcd_4d_cnt( //4位十进制计数器 input clk, input reset_n, input en, //同步使能 input load, //同步装载 input [15:0] d, output reg [15:0] bcd ); always @ (posedge clk or negedge reset_n) if(!reset_n) bcd <= 0; else if(load) ...
If 8 shifts have taken place, the BCD number is in theHundreds,Tens, andUnitscolumn. If the binary value in any of the BCD columns is 5 or greater, add 3 to that value in that BCD column. Go to 1. Example 1: Convert hex:0xE to BCD Example 2: Convert hex:0xFF to BCD Truth ...

这样圈的话看似是最简:SOP = bcd;但是我们换一种方法,把D也圈在内,因为D属于don't care值 这样圈之后 SOP = ~acd + acd 化简后 SOP = cd,为最简了。 所以SOP圈法如下: POS圈法也同上,可以将D值也圈在内来: POS也可以这样圈: 代码如下 代码语言:javascript 代码运行次数:0 运行 AI代码解释 module...
As I understand, CLK is the hour clock, and you want to use this clock to count from 0 to 12 in a BCD sequence and display the result on two 7-segment LEDs as the hour, right? I would do it as the following: module decimal_counter_20(A,B,CLK,RST); input CLK, RST; ou...
