跑马灯VHDL程序

曼彻斯特编码技术用电压的变化表示0和1。规定在每个码元中间发生跳变。高→ 低的跳变表示0，低→ 高的跳变表示为1。每个码元中间都要发生跳变，接收端可将此变化提取出来作为同步信号，使接收端的时钟与发送设备的时钟保持一致-Manchester coding techniques that use voltage changes in 0 and 1. Provisions in the middle of each symbol hopping happen. High → low hopping express 0, low → high jump for the express one. Symbol between each transition must happen, this change in the receiver can be extracted as a synchronization signal to the receiving end of the clock and send the equipment to maintain the same clock

:针对现场可编程门阵列(FPGA)芯片的特点,研究FPGA中双向端口I/O的设计,同时给 出仿真初始化双向端口I/O的方法。采用这种双向端口的设计方法,选用Xilinx的Spartan2E芯片 设计一个多通道图像信号处理系统。-: For field programmable gate array (FPGA) chip features of FPGA in the bi-directional port I/O design, the simulation is initialized at the same time two-way port I/O method. Using this design method of two-way ports, optional Spartan2E the Xilinx chip to design a multi-channel image signal processing system.
