设计遥控器接收解码电路。该电路接收编码后的串行数据，解码输出数据。电路接收 到的串行数据的格式为： 4 位同步码“ 1010”， 4 位数据（高位在前）， 1 位奇校验码（对前 8 位数据校验）(Design of remote control receiver decoding circuit. The circuit receives the encoded serial data and decodes the output data. The format of the serial data received by the circuit is: 4 bit synchronous code "1010", 4 bit data (high in the front), 1 bit parity check code (check for the first 8 bits of data))

it performs the serail dividing operations

说明：  本代码是控制DS1302的VHDL代码，浅显易懂，方便修改，注意看data sheet，保证时钟和各个延迟满足要求即可(This code is to control the DS1302' s VHDL code, easy to understand, easy changes, note the data sheet, ensure the clock and can meet the requirements of the various delays)

说明：  实现了从摄像头读取数据到液晶的显示，利用了cycloneV 和康欣的开发板资源(It realizes the display of reading data from camera to liquid crystal.)

说明：  可调矩阵，最大32*32位浮点数乘法矩阵及仿真。(32*32 floating multiplication matrix)

本代码是用VRILOG语言写的SDRAM的控制器的标准代码,供开发SARM参考.-this code is used to write the language VRILOG SDRAM controller standard code for the development of SARM reference.

说明：  数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)
