Design and Implementation of a kind FP GA as the core real-time spectrum analysis system. System includes real-time spectrum monitoring and real-time spectrum analyzer two kinds of spectrum analysis mode. Real-time spectrum monitoring mode using the FFT algorithm design and implementation for real-time monitoring of the signal real-time spectrum analyzer mode using DFT algorithm design and implementation, for a detailed analysis of the signal. Experimental results show that the system takes full advantage of FP GA chip resources, with real-time, spectral analysis parameters adjustable, multi-channel switching cycle analysis and so on. The spectral analysis of the current system has been successfully applied to a two-way HFC network and back-channel noise being monitored. (2015-02-28, VHDL, 213KB, 下载12次)
使用vhdl语言设计的乒乓球比赛游戏机，一个由甲乙双方参赛，有裁判的三人乒乓球游戏机。用8个发光二极管代表乒乓球台，中间两个发光二极管兼做乒乓球网，两边各代表参赛双方的位置，用点亮二极管按照一定方向移动来表示球的运动。在游戏机的两侧各设置两个开关，一个是发球开关（af，bf），另一个是击球开关（aj，bj）。甲乙二人按乒乓球比赛的规则来操作开关。
点亮，代表乒乓球在移动。比赛一直进行到一方几分为11分，该局结束，记分牌清零，可以开始新的一局比赛。
Using VHDL language design table tennis game consoles, a competition by both parties, the referee of three table tennis game. Double as a table tennis net with eight light-emitting diodes on behalf of a ping-pong table, in the middle of two light-emitting diodes, on both sides of the representatives participating both lit diode according to a certain direction to move to represent the movement of the ball. Setting two switches, each on both sides of the ride is a tee switch (af, bf), another is batting switch (aj, bj). B two table tennis competition rules to operate the switch. On behalf of table tennis in mobile. The game has been carried out to the party a bit for 11 minutes it ends scoreboard is cleared, you can start a new innings. (2012-09-09, VHDL, 481KB, 下载9次)
文章描写了基于乒乓球比赛游戏机的实现程序，其实现的功能为：
(1) 该设计是由甲、乙双方参赛，有裁判的三人乒乓球比赛游戏机。
（2）用13个LED排成一条直线，以中点为界，两人的乒乓球游戏机是由13个LED组成的模拟乒乓球台，用点亮的发光二极管按一定的方向移动来代表球的运动，在乒乓球游戏机中设计甲乙球拍按钮，以此来实现选手的击球。
（3）当“球”（点亮的那只LED）运动到某方的最后一位时，参赛者应能果断地按下位于自己一方的按钮开关，即表示启动球拍击球。当甲按动乒乓球开关时，靠近甲方的第一个发光二极管亮，然后发光二极管由甲方方向依次点亮，代表乒乓球的移动。当球过网后按照设计者规定的球位乙方就可以击球。若乙方提前击球或者未击到球，则甲方得分。然后重新发球进行比赛。每隔两次交换发球权。
（4）设置自动计分电路，甲乙双方各用7段译码管进行计分显示，11分一局，每满11分为一局，然后计分清零，重新开始新一局得比赛。
（5）电路中设计了犯规提示，比赛进行中，选手连续两次获得发球权后，如果发球权未交与对方或者未获得发球权方发球，此时犯规音响就会响起。
The article describes the realization of the program based on table tennis game consoles, to achieve the functions of:
(1) was designed by A, B sides play, the referee of three table tennis game.
(2) with 13 LEDs arranged in a straight line, the midpoint of the two table tennis game simulated table tennis table is composed of 13 LEDs lit light-emitting diode according to the direction of movement to represent the ball movement, in the table tennis video game design B racket button in order to hit the ball players.
(3) When the "ball" (lit bird LEDs) movement to a party last one, participants should be able to decisively press in their side of the button switch, that means start the racket hit the ball. A press table tennis switch, the first near the Party a LED lights, and then the light-emitting diodes were lit by the Party direction, on behalf of table tennis movement. When the ball over the net in accordance with the the designer provisions ball B can be shot. If Party B in (2012-02-16, VHDL, 10KB, 下载4次)
