upp 接口，verilog

说明：  basic verilog code on siso, piso, sipo

海德汉绝对式编码器代码，VHDL语言编写(Heidenhain absolute encoder code, VHDL language)

此为华远显示320*240LCD驱动程序，该程序也适用于带RA8806控制器的LCD(This is the Huayuan display 320* 240LCD driver, the program also applies with RA8806 LCD controller)

说明：  这是32位移位寄存器，是用verilog编写的，能够实现从1到31位的左或右的移位(This is a 32-bit shift register, is prepared verilog, can be realized from the 1-31 shift left or right)

说明：  该文件包含了实现单周期cpu的全部代码以及实验报告，包括仿真波形以及烧板过程(This file contains all the codes and experimental reports of realizing single cycle CPU, including simulation waveform and download process)

(1) 与微处理器可编程三态总线接口 GPIO （通用目的输入和输出端口）(2) 总线接口：1.addr_reg： 地址总线2.rd_n_reg、 wr_n_reg、 cs_n_reg： 控制总线3.数据： 三态数据总线(3) 内部寄存器：

代码是一个复数乘法器，两个复数相乘，只用到了2个实数相乘，运算量少(Code is a complex multiplier, two complex multiplication, uses only real number multiplied by 2, operations less)

HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)

说明：  FPGA实现的AD采样控制程序的源码，欢迎大家下载(FPGA implementation of the AD sampling control)
