使用VHDL编写语言，巧妙的利用计数器和循环输出一个坐标系，由于VHDL出现负数比较麻烦，全部由正数代替，输出一个原点在中心，半径128的256×256的坐标。方便坐标变换以及用此坐标做算法。(Use of VHDL language, clever use of counter and loop outputs a coordinate system, because VHDL negative too much trouble, all replaced by a positive number, the output an origin at the center, radius 128 256 256 coordinates. Convenient coordinate transformation and coordinate to do with this algorithm.)

用verilog语言的实现FIFO存储器，以先进先出的方式处理数据(The FIFO memory is implemented in Verilog language, and data is processed in FIFO)

用窗函数法设计一个线性相位FIR数字低通滤波器，用理想低通滤波器作为逼近滤波器，通带截止频率为0.2 ，阻带截止频率为0.4 ，阻带衰减不小于-40dB。(Window function method to design a linear phase FIR digital low-pass filter, as an ideal low-pass filter for approximation filter passband cutoff frequency of 0.2 stopband cutoff frequency of 0.4, the stop-band attenuation of less than-40dB.)

鉴于stm32在keil平台上的ADC采集转化，在LCD屏上显示程序(voltage acquisition adc)

基于FPGA的任意波形信号发生器,可实现频率、幅度、相位的调节，输出方波、正弦波、锯齿波(Arbitrary waveform generator based on FPGA)

说明：  国外的CIC补偿滤波器设计文件，非常有用(Abroad, CIC compensation filter design files, very useful)

VHDL的源码100例，包括加法、减法、存储、触发等，是初学者、开发人员的必备手册-VHDL source code of the 100 cases, including the addition, subtraction, storage, trigger and so on, is for beginners, developers must Manual

基于fpga的spi通信测试 可与stm32进行spi通信测试(SPI communication test based on FPGA can test SPI communication with stm32)

verilog编程语言的讲解，有电子科技大学出版(verilog programming language to explain, there is the University of Electronic Science and Technology Publishing)
