BCD 2 格雷码转换器

vhdl编写的FPGA与DSP接口程序，在FPGA内分配了两块双BUFFER与DSP进行通信(vhdl prepared FPGA and DSP interface program, the FPGA within the allocated 2 pairs of BUFFER to communicate with the DSP)

VIVADO SOC 使用文档 基于zynq 7020(vivado soc example text of zynq)

这是一些小代码的集合 希望能对大家有所帮助(This is a collection of some small code for all of us hope to be helpful)

用verilog写的，基于查表法实现的LOG10运算器，在Altera FPGA中应用。(It is a verilog design of LOG10 calculation unit, which is based on LUT arithmatic. And it is applicated in Altera FPGA.)

基于SDRAM的PCI采集,上位机为VC编写，桥芯片为PLX9054，项目已经做完，上传5个例程，已经验证通过(SDRAM, PCI-based acquisition, PC for VC preparation, bridge chip for PLX9054, the project has been done, upload 5 routines, has been verified by)

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.

说明：  本书介绍基于FPGA实现数字信号处理的原理与方法，作为Xilinx公司相关课程的培训教材(The FPGA implementation of DSP principle & method.)

PLL，即锁相环。是FPGA中的重要资源。由于一个复杂的FPGA系统往往需要多个不同频率，相位的时钟信号。所以，一个FPGA芯片中PLL的数量是衡量FPGA芯片能力的重要指标。FPGA的设计中，时钟系统的FPGA高速的设计极其重要，一个低抖动, 低延迟的系统时钟会增加FPGA设计的成功率。 本实验将通过使用PLL, 输出一个方波到开发板上的SMA接口来给大家演示在ISE软件里使用PLL的方法。
