Description: --功能描述
--1 刷卡后产生与本人身份唯一对应的串行二进制码元序列，作为模拟系统的输入信号（此处不妨设为8位学生学号）。
--2 经过串并转换，序列变成一个8位二进制数。
--3 遍历预先存储在rom中的学号信息，逐一和这个8位数相比较，如果有相匹配的信息，显示欢迎字样（此处用一个高电平表示），同时打开栅栏门（也用一个高电平表示）。

Description: 移位运算器SHIFTER 使用Verilog HDL 语言编写，其输入输出端分别与键盘/显示器LED 连接。移位运算器是时序电路，在J钟信号到来时状态产生变化， CLK 为其时钟脉冲。由S0、S1 、M 控制移位运算的功能状态，具有数据装入、数据保持、循环右移、带进位循环右移，循环左移、带进位循环左移等功能。
CLK 是时钟脉冲输入，通过键5 产生高低电平M 控制工作模式， M=l 时带进位循环移位，由键8 控制CO 为允许带进位移位输入，由键7 控制:S 控制移位模式0-3 ，由键6 控制，显示在数码管LED8 上 D[7..0]是移位数据输入，由键2 和1 控制，显示在数码管2 和1 上 QB[7..0]是移位数据输出，显示在数码管6 和5 上:cn 是移位数据输出进位，显示在数码管7 上。-SHIFTER shift calculator using Verilog HDL language, the input and output side with the keyboard/display LED connection. Shift operator is a sequential circuit, in J when the bell signals the arrival of a state of change, CLK its clock. By S0, S1, M to control the functions of the state of shift operations, with data loading, data maintenance, cycle shifted to right, into the digital cycle shifted to right, circle left, circle to the left into the digital functions.
CLK is the clock pulse input through the key high 5 low M mode control, M = l-bit cyclic shift into when, controlled by the key 8 into the displacement of CO to allow input from 7 control keys: S Control Shift Mode 0-3, 6 button control from showing in the digital control LED8 on D [7 .. 0] is the shift data input from the keys 2 and 1 control, displayed in the digital tube 2 and 1 QB [7. .0] is the displacement data output, displayed on the LED 6 and 5: cn is a binary data output shift, showing 7 on in the digital co Platform: |

Description: 序列检测器可用来检测一组或多组由二进制码组成的脉冲序列信号，这在数字通信领域有广泛的应用。当检测器连续收到一组串行二进制码后，若这组码与检测器中预制的码相同，输出为A，否则输出为B。序列检测I/O口的设计如下：设Din是串行数据输入端，clk是工作时钟，clr是复位信号，D是8位待检测预置数，QQ是检测结果输出端。-Sequence detector can be used to detect one or more sets consisting of binary code from the pulse sequence signal, which is a broad field of digital communication applications. When the detector continuously received after a group of serial binary code, if this group of pre-code and the code detector in the same output as A, otherwise the output B. Sequence detection I/O port design are as follows: Let Din is the serial data input, clk is work the clock, clr is a reset signal, D is the 8-bit preset number to be detected, QQ is the test results output.
