在 VHDL 乒乓 P 楚方法之后写的定时器模块

UART communication on SPARTAN 6 it contains tx and rx

步进电机位置系统 步进电机位置系统block symbol file 步进电机位置系统的Verilog HDL程序设计 已编译通过-Stepper motor stepper motor position location system system block symbol file location stepper motor system Verilog HDL program design has been compiled through

基于Verilog的数码管模拟扫描程序，分为两种显示方式，一种是数码管逐个显示，另一个是所有数码管一起显示。-Verilog-based digital control analog scanning procedures, two types of display, a digital control-by-show, and the other is with all digital tube display.

这是基于Quartus2 开发环境和verilog hdl语言写的38译码器(This is based development environment and Quartus2 verilog hdl language used to write decoder 38)

基于Verilog HDL的SDRAM控制器。 实验条件： 工具：Quartus II 6.0 ,SignalTap II FPGA：Altera Cyclone EP1C12Q240C8N SDRAM：HY57V283220T-6(SDRAM controller based on Verilog HDL. Experimental conditions: Tools: Quartus II 6.0, SignalTap II FPGA: Altera Cyclone EP1C12Q240C8N SDRAM: HY57V283220T-6)

xilinx的时序约束实验，通过阅读本文档，你可以用全局时序约束来轻松提高已有的项目的系统时钟频率，同时你还可以用映射后静态时序报告以及布局布线后静态时序报告来分析你的设计性能(Xilinx timing constraints of the experiment, by reading this document, you can use the overall timing constraints to easily enhance existing projects the system clock frequency, at the same time you can also use static timing report after mapping, as well as after placement and routing static timing analysis report to you design performance)

fpga，主要功能是实现n*n图像的旋转，源程序代码，(fpga, main function is to achieve the n* n image rotation, source code,)

logic lock 的vhdl源码，altera平台适用。-logic lock the VHDL source code, altera platform.

請設計一個8位元移位暫存器，規格如下： 當控制線S1，S2輸入為00時，平行載入； 當控制線S1，S2輸入為01時，在一時脈內向右shift 1位元； 當控制線S1，S2輸入為10時，在一時脈內向右shift 2位元； 當控制線S1，S2輸入為11時，在一時脈內向右shift 3位元 (Serial Adder)
