UART 变送器

一個紅外線感測電路的設計，是經由opa來設計。(An infrared sensing circuit design, is designed by opa.)

全自动洗衣机的控制器。 1.洗衣机的工作步骤为洗衣、漂洗和脱水三个过程，工作时间分别为：洗涤10秒，漂洗5秒，脱水5秒； 2.用一个按键实现洗衣程序的手动选择：A、单洗涤；B、单漂洗；C、单脱水；D、漂洗和脱水；E、洗涤、漂洗和脱水全过程； 3.用显示器件显示洗衣机的工作状态（洗衣、漂洗和脱水），并倒计时显示每个状态的工作时间，全部过程结束后，应提示使用者； 4.用一个按键实现暂停洗衣和继续洗衣的控制，暂停后继续洗衣应回到暂停之前保留的状态； (Automatic washing machine controller. 1 washing machine work steps for the laundry, rinsing and dehydration three processes, working hours are as follows: washed for 10 seconds, rinse for 5 seconds, dehydrated five seconds 2 with a button to manually select the program to achieve laundry: A, single-washing B, single rinse C, a single dehydration D, rinsing and dehydration E, washing, rinsing and dehydration the whole process 3 with a display device display the working status of washing machine (laundry, rinsing and dehydration), and each state countdown show working hours, after the whole process should prompt the user 4 laundry with a button to pause and continue control of laundry, laundry should be back after a pause pause before continuing to retain the state )

此代码是SPI接口的Master的Verilog源代码，经上板测试是没有问题的，请大家放心使用 (This code SPI Interface Master of Verilog source code, there is no problem on board test, please rest assured to use)

题目来源于学校的课题系统硬件综合设计，代码中有单周期CPU设计，多周期流水线CPU设计，使用的是Verilog语言，多周期的是基于MIPS架构。

由8 位加法器构成的以时序方式设计的8 位乘法器，采用逐项移位相加的方 法来实现相乘的VHDL程序代码。包含几个小模块和一个顶层设计文件，运行可用。(an 8 bit multiplier combined with 8 bit adder using a design by way of timing,and it use a way of Itemized shift to implement the multiply.It include some little module and a top level design document.)

蓝牙是一种标准协议的设备 （如手机、 掌上电脑、 个人电脑和任何其他设备之间的无线连接。这一标准的主要目的是提供免版税标准这种无线协议。这个项目的目标是打造 HCI LMP，开源免费蓝牙基带控制器和高层次软件栈

能够实现16位的SDRAM的读写，没有仿真文件，只有SDRAM读写的源代码，用Verilog编写(can complete read or write sdram， only include Verilog code and no simulation files)

verilog HDL语言程序，运行后3*3矩阵键盘按键控制实验板led依次点亮，达到流水灯的效 果

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

本模块是实现格雷码和二进制码的转换，并给出仿真测试文件(This module is to achieve the conversion of Gray code and binary code, and give the simulation test file)
