AMBA BUS AHB/APB 的Verilog实现

用verilog语言写的简单的键盘扫描代码，适合初学者，用alter的软件编写的程序代码。(Using verilog language to write simple keyboard scan code, suitable for beginners, with alter software program written code.)

是基于FPGA的5620的数模转换芯片底层的应用程序，希望有用。(Is a digital-analog converter chip underlying the 5620 FPGA-based applications, and I hope useful.)

基于AD9226的ad转换程序资料，从采集到数位转换再到模量转换(AD conversion program data based on AD9226)

基于VHDL语言的CORDIC算法实现，用于计算sin(x),cos(x)等，实测可用(Based on VHDL CORDIC algorithm, used to calculate sin (x), cos (x), etc., the measured available)

资源描述数据传输发生在芯片内部，在芯片内部和系统之间也有。因为它是异步时钟，将没有方法来建立时钟分配技术。

基于NiosII系统的可以在DE2-115板子上运行的吞食蛇游戏！（可以使用RS2键盘进行控制）(DE2-115 board NiosII system swallowed snake game! , (RS2 keyboard control))

说明：  PID算法用verilog语言实现，实测可用，由三个模块组成(The PID algorithm is implemented in Verilog language. The actual measurement is available. It consists of three modules.)

AES加密算法verilog源码 This project is the hardware implementation of the  Advanced Encryption Standard with a key size of 128 bits. The implementation adheres to the FIPS-197 document which explains the same.The core can do both encryption as well as decryption.The documents aes_arch.doc and aes_tb_readme.txt give further details of the rtl implementation and test bench respectively. This code was written originally with 128 bit ports for both input and key but later converted to 64 bits each to save on i/o pins. It can be reverted back easily if one just changes the port widths and dispenses with the load signal in the top module and making approriate changes in process where load is used.Synthesis results have been included for Xilinx Spartan-3 device.The directory structure of the project is as under- AES128
