SPI_slave代码，已经实用！

说明：  可以进行连续uart串口读写999次以上不出错，已经检测成功(It can read and write serial UArt more than 999 times without error. It has been detected successfully.)

调试bcm5396，写入和读取内部寄存器功能。功能验证可以用(Debug bcm5396, write and read the internal register function. Functional validation can be used)

VHDL黄金参考手册，能让你更好的学习了解VHDL语言(VHDL gold reference manual, can make you a better learn VHDL language)

说明：  本文设计了基于FPGA的，用verilog HDL语言描述的在伽罗华域GF（ ）上的RS（6,4）编码器。在ISE软件上用verilog HDL语言分别对每个模块进行描述，然后在软件上进行编译、仿真，最终实现RS（6,4）编码，下载之后用chipscope采集数据，分析符合仿真结果，达到设计的要求。(This paper is designed based on FPGA, described by Verilog HDL language in Galois field GF () on RS (6,4) encoder. Using the ISE software Verilog HDL language for each module is described, and then compile, simulation in software, the ultimate realization of the RS (6,4) encoding, after downloading by chipscope data acquisition, the analysis with the simulation results meet the design requirements.)

FPGA实现反正切功能，工程原件，包括测试文件，能够很好实现该功能(FPGA implements arctangent function, original engineering)

视频编解码设计中会有涉及到图像操作代价的计算，其中通用算法lamda的计算是一个可以模块化设计的模块，代码就是实现这个功能而设计的。

基于BCH码的ECC纠错算法，可纠错2位错误码，供参考(Based on BCH code ECC error correction algorithm, two error codes can be corrected for reference.)

429总线通过FPGA直接实现发送程序,通过Verilog实现(send 429 message by Verilog and FPGA )

此代码是实现DPA。
