机器人线跟踪

SDRAM即同步动态随机存储器，同步是指memory工作需要同步时钟，内部命令的发送与数据的传输都以它为基准；动态是指存储阵列需要不断地刷新来保证数据不丢失；随机是指数据不是线性依次存储，而是自由指定地址进行数据读写

说明：  基于FPGA，用verilog hdl语言实现串口收发实验(Based on FPGA, using Verilog HDL language to achieve serial port transceiver experiment)

Multipleksor 3 to 1 - 3x1bit in, 1x1bit out

4 bit convoltion with vhdl.

Aurora协议是一款高带宽、低成本、可扩展、框架简洁、适合点对点串行数据传输的协议。(Aurora protocol is a high-bandwidth, low-cost, scalable, simple framework for point to point serial data transfer protocol.)

LTE上行链路使用的DFT-S-OFDM系统的仿真，其中包括QPSK星座映射、串并转换、N点DFT、子载波映射等。(LTE uplink using the DFT-S-OFDM system simulation, including QPSK constellation mapping, string and conversion, N-point DFT, subcarrier mapping, etc..)

说明：  XC7A35TCSG324-1的Verilog频率计程序，支持十分频，支持切换内外信号输入(Verilog frequency meter program of xc7a35tcsg324-1 supports decadal frequency division and switching internal and external signal input)

实现24小时计时，因为位数不够，这里是12进位，可自行调整进位数(Realize 24-hour timing, because the number of digits is not enough, here is 12 carry, you can adjust the carry number by yourself.)
