一个AXI slave的Verilog实现代码，内部有基于UVM编写的testbench,该slave是基于AXI3协议来实现的，可以给初学者一些启示

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

主要用于信道编码，可以防止相位的翻转，计算码元之间的相位变化以后，做差分传输，接收端根据前一码元的相位进行解差分。

应用背景i2cSlave is a minimalist I2C slave IP core that provides the basic framework for the implementation of custom I2C slave devices. The core provides a means to read and write up to 256 8-byte registers. These registers can be connected to the users custom logic, thus implementing a simple control and status interface.关键技术The core has up 256 registers that can be accessed via I2C. I2C write operations are used to set the register address pointer, and write the register data. I2C reads are used to read the register data. Successive data reads or writes result in data being read or written from incremental register addresses. There is no limit on how much data can be read or written in a single access, but the internal register address pointer will wrap round to 0 once it reaches 255. Note that the address pointer is not initialized at reset, and the address pointer must

说明：  这是32位移位寄存器，是用verilog编写的，能够实现从1到31位的左或右的移位(This is a 32-bit shift register, is prepared verilog, can be realized from the 1-31 shift left or right)

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

VGA的verilog实现，通过宏控制输出格式，兼容altera的avalon总线。
