UART的Verilog代码

与IP核配套的I2C-Master Core，包含了目前主流FPGA芯片的I2C实现，代码包括Altera/Xilinx/OpenCore等公司的VHDL/Verilog/C等。(I2C-Master Core)

vhdl 让你更加熟悉掌握这么硬件电路设计语言 非常清晰(vhdl)

NIOSII I2C接口模块及驱动程序，并含有测试程序。对想开发NIOS的工程师很有帮助(NIOSII I2C interface module and driver, and contains the test procedures. NIOS of engineers want to develop useful)

程序是自己编写的，程序的主要功能是实现VGA显示。显示画面为“生日快乐”，并且显示有蛋糕图形。生日快乐四个字可在屏幕上进行流动显示。

说明：  高速流水的SDRAM控制器，最高速度可达速度在200M左右(high speed SDRAM controller)

此代码可以实现16位二进制和BCD码之间的转换。(This code can realize the conversion between 16 bit binary and BCD code.)

进阶实验之SRAM测试，由verilog编写，可直接对sram进行存写(Advanced SRAM test experiments, written by the verilog, can be stored directly on the sram write)

saber的仿真模型，是一个电源的，经过调试已经成功(The simulation model of the saber, is a power, after commissioning has been successfully)

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)

FIR带通、带阻滤波器设计，需要输入截止频率以及容许偏差。(FIR band pass and band stop filter design)
