it performs the serail dividing operations

用VHDL写的源代码程序，包涵三人表决器，七人表决器，全加器以及模24，模60的计数器，都是单文件的，由于程序小又多，所以集中在一起，供新学习VHDL语言的朋友们参考。-With VHDL source code written procedures, includes three of the voting machine, vote on seven people, and full adder, as well as modulus 24, modulus 60 counters, are single-file, as many small procedures, so together for the new Learning VHDL Language Reference friends.

GMSK调制基带眼图仿真源代码，基于MATLAB(GMSK modulation baseband eye diagram simulation source code, based on MATLAB)

应用背景在本文中，我们提出了流水线的吞吐量的AES-GCMkaratsuab人基于有限域乘法器。与我们提出的四级子二次有限域乘法器，Ghash功能不在GCM任何瓶颈硬件系统，无论三的AES实现哪一个提高吞吐量的AES-GCM流水线Karatsuba乘法器203（基于BlockRAM SubBytes，复合场SubBytes或基于LUT的SubBytes）。这个提出的AES-GCM芯达到31gbps和39gbps Virtex4吞吐量和Virtex5，分别。实验结果表明，一个单一的现代FPGA芯片能提供超过了认证的AES-GCM 30Gbps的吞吐量，具有高性能计算领域可编程器件的优点系统。关键技术在AES-GCM的两种主要成分（高级加密标准伽罗瓦计数器模式）是一个AES引擎和一个有限域乘法器GF（2128）在通用散列函数（GHash）。因为固有的计算反馈，系统性能通常由有限的基于FPGA实现的已知域乘法器的日期。在本文中，我们目前的吞吐量优化的AES-GCM 4级流水线基于FPGA的Karatsuba-Ofman算法的有限域乘法器。关键流水线乘法器的延时然后匹配的AES实现无论BLOCKRAM SubBytes，流水线复合场SubBytes或基于LUT的字节。AES-GCM吞吐量超过30Gbps上一个单一的Xilinx Virtex芯片。实验结果表明，我们实现迄今为止最有效的AES-GCM FPGA实现。

LDPC encoder and decoder, very simple

利用FPGA开发板的PCIE接口实现数据的传输和发送。(Using the PCIE interface of FPGA development board to realize data transmission and transmission.)

this is "AND" gate implementation in VHDL

Xilinx的FPGA开发DEMO例程，功能相对来说比较全面，适合新手参考。-Xilinx FPGA development DEMO routines, function relatively comprehensive reference suitable for novice.

说明：  how to come ture a costas loop in FPGA with verilog,it is very useful on project

This is an UART real time clock
