SPWM信号产生系统IP软核设计及验证
针对电力电子领域的需求，采用自然采样法设计了一个全数字三相SPWM信号产生系统IP软核．通过数字频率合成技术实现了对电源频率的辅确控制．使电源频率精度达到16位．其中。通过调节控制参数．分别实现了电源频率与载波频率的7级、8级控制．最后。搭建了基于FPGA的测试系统．验证了系统功能的正确性．(According to the requirement of power electronics, the natural sampling method for the design of a full digital three-phase SPWM signal generation system. The power frequency of IP core is the auxiliary control is implemented through digital frequency synthesis technology. The power frequency accuracy of 16. By adjusting the control parameters, 7 and 8 levels of power frequency and carrier frequency are realized respectively. Finally, the control of the power frequency and carrier frequency is realized. A test system based on FPGA is built, which verifies the correctness of the system function)

加密算法的 VLSI 实现
你好，每一个
这是实现的 RC4 加密算法，开发基于从互联网采取的想法
它是非常易于使用：
的步骤： 1：首先，发出复位 (rst)
步: 2:将密码字节--加载到的 password_input 端口。密码的长度是 KEY_SIZE
一步： 3：执行密钥扩展的问题 768 时钟
一步： 4：该模块丢弃根据 RFC 4345 流的第一次弱字节 1536年时钟稍候。
一步： 5：现在，您应该开始接收通过输出总线，一个字节的伪随机流每个时钟。Output_ready 信号信号在输出 K.当存在一个有效的字节时
加密：
通过互联网通信需要对传输数据的每一位应该是很高安全加密虽然因此转移 RC4 来玩。这种算法瀑布流密码，可在其中一点一点地执行加密的类别下。

数字频率合成原理
就是生成原始波形数据，设计Verilog代码，把数据加载到初始ram中，再调用数据进行仿真，仿真实现波形还原，和进行合成之类。

FPGA实现UART接收和发送
在fpga中实现实现了UART的功能，经过实际在ep4cE6 fpga上下载测试，发现可以准确的接收个发送串口数据，和板子上的单片机uart通信正常。要使用的小伙伴，可以直接拷贝使用。

-Elliptic
We present elliptic curve cryptography (ECC) coprocessor,
which is dual-field processor with projective
coordinator. We have implemented architecture for scalar
multiplication, which is key operation in elliptic curve
cryptography. Our coprocessor can be adapted both prime field
and binary field, also contains a control unit with 256 bit serial
and parallel operations , which provide integrated highthroughput
with low power consumptions. Our scalar multiplier
architecture operation is perform base on clock rate and produce
better performance in term of time and area compared to similar
works. We used Verilog for programming and synthesized using
Xilinx Vertex II Pro devices. Simulation was done with Modelsim
XE 6.1e, VLSI simulation software from Mentor Graphics
Corporation especially for Xilinx devices.
