微机原理fpga实验报告

基于FPGA开发板的实201313/1是利用FPGA模块实现对逻辑门电路的调试。队员在实验的过程中，不仅学习了（HardwareDescriptionLanguage，硬件描述语言）ISEFPGA板子的结验，8255FPGA板子，大家都花费LEDLED灯，并且作FPGA模拟设置基础硬件，实现冯-诺依曼架构计算机基（3）8255实验：通过FPGA强大的功能实现了8255并行通讯，并且结合8255的设计 实验 FPGALED的功能。/LED（3）8255

RS232模块做串口通讯；8255模块为我们模拟的主要其中数据处理模块担负一切数据处理工作，他处理进入的数据，包括RS232的通讯数CPU写端口来改变对总线模块上的优先级进行编程，CPU每次输BUG，同时也易于对比本次实验所用XC3S50是Spartan3A系列中最的一款，总共50k逻辑门，70411KB，两个数字时钟管理单元，364个差分输出端口。MicroblazeDW8051软核，发现逻辑资源IOXC3S200就可以满足要求；但是基本可以满足实验的需求，而且轻量化的方便资源的分配，同时也避免了大面积造成的电路不稳定问题。80C51用用。总线的物理层为标准的双绞线和DB9接头RS232DB25接口，IBMPCRS-232DB9连接器，后来成为事实标准，DB25反而没有什么人应用了。现在绝大多数笔记本电脑上已经不再配备DB9串口接头，所以采用PL2303将串口转换USBUART功能。（1）CPUCPU18.432MHzCPU内部的软件上做改变。其实对于前两个实（2）8255CPU根据定义，825588D0～D782553个A、B、CA、B、C口及控制寄存器，故地址线为两根DBD0～D78255CPU8根据定义，82553A、B、C8825524（2）BPB0～PB782558（3）C口：编号为PC0～PC782558LEDLED8段共阴数码管，所以对应字符的每笔画端口拉高电平的时候，该笔画点1234567890对应输出端UART9600bit/s1120UCLK时钟周期。188个时钟周期，则认为起始以后，TXD端口要保持高电平，这样接收方才可以顺畅的接收到发送的数据。LED模块的输出。HDL完成设计文件，然后由计算机自动地完成逻辑编译、化简、分割、综合、优化、eda软件进行设计时需要对其内部原verilogise为基础进行介绍hdlverilog写的程序实际上是写的一段实实在在edahdlverilog语言编好程序后，整个设计的基础算是打好了，在进行下一步逻辑综合之multisimeda软件ise只要在源文件的基础上再生成一个测试文件就可以进行仿真了。以下是仿真界面师只给出了功能描述，却没给出布线图，于是最后作出来的电路都是五花八门的。eda软件都要通过这一ise综合后得到的（rtl级模型（ise中，步骤会对选定的器件进行最终的配置，优化，布局布线，并产生可以到fpga中ise中这两个功能被包含在了一起eda软件的不同而有差异，但是对于以上eda适应起来也会相当快的。可编程输入/输出单元简称I/O单元，是与外界电路的接口部分，完成不气特性下对输入2-4FPGAI/O按组分类，物理特性，可以调整驱动电流的大小，可以改变上、下拉电阻。目前，I/O口的频率也越来FPGADDR2Gbps的数据速率。FPGA了。BIOSParallelPortEPP+ECP（增强型并口）模2ISECPU111CPU和中断控制器之间的联络线，CPU确实已经接1CPUNCPU需要的一系列寄存器，包括中断NNNNRNRIT_aa这里面包含了对应中断的中断号，或者中断向量N根据大小N应位置1.CPU和控制器约定好的。XilinxIDE漂亮和仿真方便（ISIM，虽然没有强大但是足够了毕竟就是看看波形之外和QuartusII比没有任何优势。另外，XC3S50slice704个，blockRAM4KBAltera同级别的飓风系列可以说性能上完全被秒杀就连Microblaze都没法运行导致XilinxSDKverilogC代码好一点，Verilog语言进行开发，当然就算是VHDL，其实区别也不是很大。关于这块板子的串口收发问题：直接接好的DB9接头无论如何都没有现象，而非直接接Verilog语法及使用方法，初步Verilog的初步应用。正是老师，助教同学对我的帮助，才能让我顺利完成实验。八.附8255moduleinputoutputwireregregselect_flag,write_flag,read_flag;reg[7:0]out_buf_1;reg[7:0]reg[7:0]reg[7:0]reg[5:0]clk_cout;regclk_range;wireclk_internal;reg[5:0]cout_wr;reg[5:0]reg[5:0]reg[5:0]reg[5:0]reg[5:0]cout_in_num;regin_wire_busy;regin_wire_buf;regin_sample;reg[7:0]core_buf;regregout_wire_busy;regout_sample;reg[5:0]assignclk_internal=clk_range;assignin_buf=in_serial;always(posedgeclkorposedgerst)
