Quartus II VHDL语言8分频器计数器

清华大学电子课程设计：Verilog，QuartusII可正确运行，可下载到FPGA上，音乐计算器，完成两个三位数的运算，有注释，很强大！！(Verilog, QuartusII run correctly, can be downloaded to the FPGA, music, calculator, completed two three-digit operations, there are notes, very powerful! !)

说明：  altera 最新的CYCLONE IV的pci-e核的testbench，VHDL源程序。(altera latest CYCLONE IV of the pci-e core testbench, VHDL source code.)

本程序设计一个基于FPGA的4相步进电机定位控制系统。由步进电机方向设定电路模块、步进电机步进移动与定位控制模块和编码输出模块构成。前两个模块完成电机旋转方向设定，激磁方式设定和定位角度的换算等工作，后一个模块用于对换算后的角度量编码输出。-This procedure to design an FPGA-based 4-phase stepper motor positioning control system. Direction set by the stepper motor circuit module, stepper motor stepper movement and positioning control module and the code output modules. The first two modules complete the motor rotation direction setting, exciting way of setting the angle and positioning of the conversion work, after a module for the point of view of the volume of converted output encoding.

spi转i2s的verilog程序，fpga是总模块，spi和i2s是子模块，shiftreg是转换-spi transfer i2s the verilog program, fpga is the total module, spi, and i2s is the sub-module, shiftreg is to convert

在Altera公司的Quartus II软件平台下完成了基于Log-MAP算法的Turbo码编译码器的FPGA设计及实现。在Turbo码的FPGA设计与实现部分，主要针对了 Turbo码的编译码器中各个重要模块进行了设计和实现，例如编码器中RSC分量译码器、交织器，以及译码器中对数据量化和运算、E函数、SISO分量译码器（分支度量、前向递推、后向递推以及对数释然比的计算）的设计与实现。
