wallace multiplier trees for 4:2

采用Quartus2编写的电子秒表电路 实现计时、暂停等功能(Quartus2 prepared using electronic stopwatch timer circuit, suspension and other functions)

说明：  IIC 的Verilog实现，工程是在Xilinx的ISE9.1上实现的(IIC of the Verilog implementation project was implemented on Xilinx' s ISE9.1)

本例源代码文件由用户按照书中的操作步骤自己生成，“Example-2-1Project_Navigator_Demo源代码”目录下为源代码的参考文件。“Example-2-1Project_Navigator_Democounter”目录下为完整的工程，包括源代码文件、综合与实现的结果文件、ISE工程文件等，可以使用ISE工程管理器打开工程，供读者参考(In this case the source code files by the user in accordance with the steps the book itself is generated, "Example-2-1 Project_Navigator_Demo source" directory as the source code reference document. "Example-2-1 Project_Navigator_Demo counter" directory for a complete project, including source code files, integrated with the realization of the outcome document, ISE project file, etc. You can use ISE Project Manager, open the project for the reader is referred to)

FPGA连接PCI9504的电路图。以及PCB文件(FPGA connected to the circuit diagram of the PCI9504. And PCB files)

The deep lecture notes for basic digital system for cmos design

基于fpga的coms摄像头 扫描，参考文献，(Fpga based on the coms camera scan, reference literature,)

使用VHDL编写语言，巧妙的利用计数器和循环输出一个坐标系，由于VHDL出现负数比较麻烦，全部由正数代替，输出一个原点在中心，半径128的256×256的坐标。方便坐标变换以及用此坐标做算法。(Use of VHDL language, clever use of counter and loop outputs a coordinate system, because VHDL negative too much trouble, all replaced by a positive number, the output an origin at the center, radius 128 256 256 coordinates. Convenient coordinate transformation and coordinate to do with this algorithm.)

说明：  Verilog code for implementing simple ALU.
