交通灯的控制，分主干道和从路交通灯，主路优先，正常情况下，绿灯60s，红灯30S，黄灯5S(Traffic light control)

基于DE2-115开发板设计的一个数字钟，能进行正常的小时、分、秒计时功能，并分别由开发板上面的数码管显示秒（60s）、分（60min）、小时（24hours）的时间。并具有手动调整时间的功能(DE2-115 board design based on a digital clock, and enables the normal hours, minutes, seconds chronograph function, and were above the development board digital display seconds (60s), points (60min), hours (24hours) time . And has a function to manually adjust the time)

Floating Point FP multiplication is widely used in large set of scientific and signal processing computation. Multiplication is one of the common arithmetic operations in these computations. A high speed floating point double precision multiplier is implemented on a Virtex 6 FPGA. In addition, the proposed design is compliant with IEEE 754 format and handles over flow, under flow, rounding and various exception conditions. The design achieved the operating frequency of 414.714 MHz with an area of 648 slices.

说明：  FPGA数码管显示秒表实验 三种方法实现： 方法一： 对秒计数，得到（秒显示）0~9， 对（秒显示）计数，得到（分秒显示）0~5， 对（分秒显示）计数，得到（分钟显示）0~5， 注意进位时机 方法二： 对秒计数，得到（秒显示）0~9 对秒计数，得到（分秒显示）0~5 对秒计数，得到（分钟显示）0~5 方法三： 只对秒计数，分别取模 %60得到分钟显示 ************************ 余数%10得到分秒显示 （据说）取模运算占资源！！！！（也能接受？好像...） 再剩下的余数为秒显示 ************************(Experiment of Digital Tube Display Stopwatch Based on FPGA Three ways to achieve)
