等精度频率计的verilogHDL的实现,我花了好长时间才写的哦

sobel边缘检测，用于图像处理。实现了该算法在FPGA上的实现代码。(Sobel edge detection for image processing.Implementation of the algorithm to achieve the FPGA code.)

异步FIFO的实现，很经典的三段式状态机的写法。(The realization of the asynchronous FIFO, very classic three-step writing state machine.)

设计一个可容纳四组参赛的数字式抢答器，每组设一个按钮供抢答使用。抢答器具有第一信号鉴别和锁存功能，使除第一抢答者外的按钮不起作用；设置一个主持人“复位”按钮，主持人复位后，开始抢答，第一答对一次加1分，答错一次减1分

用walsh算法实现的符号数乘法器,asic流片时,可以不用公司的付费乘法器的ip core.(algorithm using the symbols multiplier, HDL-piece quantities. it is not necessary for the company's paid Multiplier ip core.)

verilog例子很丰富，几个经典的,希望对初学者有所帮助-verilog examples of very rich, a few classic, and want to be helpful for beginners

数字脉冲宽度调制，将输入的数字信号转换为对应占空比的模拟波形(Digital pulse width modulation, the digital signal is converted to the corresponding input of the duty cycle of the analog waveform)

该书介绍了英特尔的80x86CPU和一些串行通信芯片，以及汇编语言。(The book introduces the Intel 80x86CPU and some serial communications chip, and assembly language.)

Clifford E. Cummings论文合集，其中关于FIFO的设计很经典(Clifford E. Cummings collection of papers, on the FIFO design classic)
