VHDL写的PWM发生器，仿真通过，波形基本完美，可以用于直流电机的控制...

Verilog实现 spi接口的FPGA实现 通过仿真，修改后即可应用-Verilog realize spi interface FPGA to achieve through the simulation, the application can be modified

异步FIFO的设计 包括testbench 已调试成功-Asynchronous FIFO design includes testbench debug success has been

VHDL2verilog的程序，相信对大家很有帮助-VHDL2verilog procedures, I believe very helpful to everyone

一种RISC结构8位微控制器的设计与实现-The structure of a RISC micro-controller" s 8 Design and Implementation

OPSK调制解调。代码思路很清晰，也很干净(Modulation demodulation OPSK. The code ideas very clear, and very clean)

此设计采用Verilog HDL硬件语言设计,在掌宇开发板上实现. 将整个电路分为两个子模块，一个提供同步信号（H_SYNC和V_SYNC）及像素位置信息；另一个接收像素位置信息，并输出颜色信号。这样便于进行图形修改，同时也容易实现- This design uses Verilog the HDL hardware language design, realizes on the palm space development board Divides into two stature modules the entire electric circuit, provides the synchronized signal (H_SYNC and V_SYNC) and the picture element positional information; Another receive picture element positional information, and output color signal. Like this is advantageous for carries on the graph to revise, simultaneously is also easy to realize

8位十六进制频率计设计 根据频率的定义和频率测量的基本原理，测定信号的频率必须有一个脉宽为1s的输入信号脉冲计数允许信号；1s计数结束后，计数值被锁入锁存器，计数器清零，为下一测频计数周期做好准备。测频控制信号可由一个独立的发生器（FTCTRL）来产生。-8-bit hexadecimal Cymometer designed in accordance with the definition of frequency and frequency of the basic principles of measurement to determine the frequency of the signal must have a pulse width of the input signal for 1s permit pulse counting signal 1s counting after the total value was locked into the lock depositors, counters cleared for the next count cycle frequency measurement ready. Frequency control signal generator may be an independent (FTCTRL) to generate.

代码是一个复数乘法器，两个复数相乘，只用到了2个实数相乘，运算量少(Code is a complex multiplier, two complex multiplication, uses only real number multiplied by 2, operations less)
