采用VHDL英特尔8085微处理器的设计

本实例用于SDRAM完成读写功能: 先向SDRAM里面写数据，然后再将数据读出来做比较，如果不匹配就通过LED变亮显示出来，如果一致，LED就不亮。(The examples for SDRAM read and write functions.)

合并单元内GPS同步时钟的检测 合并单元内GPS同步时钟的检测-Combined unit GPS clock synchronization detection unit merger GPS synchronized clock detection

说明：  以ISE为开发环境，Verilog语言编写程序。功能：FPGA控制 LCD_1602动态显示秒表(In the development environment of ISE, Verilog language is used to write programs. Function: LCD_1602 dynamic display stopwatch controlled by FPGA)

最近组长给分配的任务，这几天一直在做，比较郁闷的是用的器件是XC400XL系列的，只有ISE4.1支持，用惯了7.1i的我还是要适应一阵子（关键4.1是一个试用版的）。挺折腾的，不说了，放上顶层模块：-。。。

本人用verilog编写的UDP协议，经测试可用。(I am prepared to use verilog UDP protocol, the test is available.)

full adder设计代码，verilog 语言描述，通过modelsim 仿真，quartus综合-full adder design code, verilog language to describe, through the ModelSim simulation, quartus integrated

在Quartus中，利用FPGA例化的存储器实现程序的BOOTLOADER的搬移(In Quartus, the use of FPGA case of memory to achieve the program' s move BOOTLOADER)

matlab怎么把数据输入到modelsim，文件读写的问题(data write and read from matlab to modelsim)

该程序是一个可完成订制化的SPI双向总线接口，时钟相位、极性，以及分频比全部可通过寄存器进行配置，已经在ISE下通过综合，占用资源少，强烈推荐 (The program is a complete custom of SPI bidirectional bus interface, clock phase, polarity, and the divider ratio can all be configured through the register, has been in the ISE through an integrated, small footprint, it is strongly recommended)

用FPGA实现SPWM波输出，其中包含三角波和正弦波(With the FPGA realization of SPWM wave output, including triangle wave and sine wave )
