FloatPoint Arithmetic

一个AXI slave的Verilog实现代码，内部有基于UVM编写的testbench,该slave是基于AXI3协议来实现的，可以给初学者一些启示

完成交通灯的所有功能，已经通过验证。希望大家多多指教。(Completion of all the features of traffic lights, have been authenticated. Hope the exhibitions.)

ADC芯片ADS8329数据采集的verilog代码，已经用在工程中，没问题。(ADC chip ADS8329 data acquisition Verilog code, has been used in the project, no problem.)

本例介绍直接合成带阻滤波器的方法，n阶滤波器能实现n个传输零点(A direct synthesis technique of a new class of bandstop coupled resonator elliptic filters is presented. Two different coupling schemes, which both include source–load coupling are used. The first coupling and routing scheme is the standard folded structure used in implementing bandpass elliptic filters with transmission zeros using resonators.)

1024 点得快速傅里叶变换算法 FPGA in verilog(1024 point FFT on a FPGA written in verilog)

传统的一个按键一个端口的方法，若要实现16个按键，则需要16个端口，而现在这个矩阵键盘的设计，16个按键，仅仅需要8个端口，如果使用16个端口来做矩阵键盘的话，可以识别64个按键，端口的利用率远远比传统的设计好的多，所以如果需要的按键少的话，可以选择传统的按键设计，如果需要的按键比较多的话，可以采用这种矩阵键盘的设计。

设计制作一个可容纳4组参赛者的数字智力抢答器，每组设置一个抢答按键； 电路具有一第一抢答信号的鉴别和锁存的功能。在主持人将系统复位并发出抢答指令后，若参加者按抢答键，则该组指示灯亮并用组别显示抢答者的组别。此时，电路具有自锁功能，使别组的抢答开关不起作用。 设置计分电路。每组在开始时预置成6分，抢答后主持人计分，答对一次加1分。(The design can accommodate a the Entrants digital intellectual Responder, each set answer in a key circuit has a first answer in the signal to identify and latch functions. Host to the system reset and sent the answer in instruction, participants answer in key, the group of the group light and display the answer in the group. At this point, the circuit has a self-locking function does not work in other groups to answer switch. Set Scoring circuit. Preset six points each at the beginning of the answer in scoring after the host, answer time, add 1 point.)
