Description: 用VHDL语言设计一个数字秒表：
1、 秒表的计时范围是0秒~59分59.99秒，显示的最长时间为59分59秒。
2、 计时精度为10MS。
3、 复位开关可以随时使用，按下一次复位开关，计时器清零。
4、 具有开始/停止功能，按一下开关，计时器开始计时，再按一下，停止计时。系统设计分为几大部分，包括控制模块、时基分频模块、计时模块和显示模块等。其中，计时模块有分为六进制和十进制计时器。计时是对标准时钟脉冲计数。计数器由四个十进制计数器和两个六进制计数器构成，其中毫秒位、十毫秒位、秒位和分位用十进制计数器，十秒位和十分位用六进制计数器。计时显示电路时将计时值在LED上七段数码管上显示出来。计时电路产生的计时值经过BCD七段码后，驱动LED数码管。-With VHDL language design digit stopwatch: 1, Stopwatch s time scope is 0 second ~59 minute 59.99 second, the demonstration longest time is 59 minute 59 second. 2, The time precision is 10MS. 3, The reset switch may momentarily use, presses down a reset switch, the timer reset. 4, Has starts/the stop function, according to the switch, the timer starts to time, presses again, stops timing. The system design divides into several major parts, including control module, time base frequency division module, time module and display module and so on. And, the time module influentials for the senary and the decimal base timer. The time is to the standard clock pulse counting. Counter by four decade counters and two senary counter constitution, a millisecond position, ten milliseconds positions, a second position and the rank with the decade counter, ten second position and ten ranks use the senary counter. When time display circuit will time the value on the nixietube to demonstrate on LED. The

Description: 在目前所发表的十六进制转化成BCD码的处法中，一般都采用移位相加的方法，其计算过程都比较费时，不适宜很多场合，且很多不适宜C语言调用。而在C语言中，有些初学者用求余的方法来做这种运算，造成程序十分臃肿。下面这段程序仿照竖式除法来进行运算，速度超快。-Published in the current hex code into a BCD at law, in general, have adopted the method of shifting the sum of its calculation is relatively time-consuming and not suitable for many occasions and many of them not suitable for C language calls. In the C language, some beginners seeking more than the method used to do this operation, resulting in a very cumbersome process. This procedure along the lines of the following vertical division to carry out operations, super-fast.
