Calculation of square roots via ASM

encoding and decoding of audio signal

adc0809的fpga时序电路接口程序-Sequential Circuits adc0809 the FPGA interface program

DE2 VGA控制代码，de2上控制VGA-DE2 VGA control code, de2 to control VGA

verilog 的东西好好用的呢，那是verilog 学习者的必备东西哦(verilog things properly used it, it is an essential learners verilog things oh)

rmii 以太网接口时序源代码，值得开发借鉴的哦(verilog hdl)

这是一个数字逻辑课程的电子表的实现，利用VHDL语言实现，初学者可以完全掌握，很有帮助。(This is the realization of the electronic timepiece a digital logic course, the use of VHDL language, beginners can fully grasp and helpful.)

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

Simple vhdl description to show numbers on 7-segment s on Altera DE2 board.

数字秒表的实现，我还写个具体的过程要求等，(there is function of clock,it very useful)

本代码实现了移位寄存器功能，初学者可借鉴学习-This code implements the shift register functions, beginners can learn to learn
