二维高斯实现的Vhdl代码

介绍了用vhdl描述的各种硬件电路的实现，基本包括各种常用的电路。-Introduction with VHDL description of a variety of hardware circuits realize, basic, including a variety of commonly used circuits.

说明：  PicoRV32 is a CPU core that implements the RISC-V RV32IMC Instruction Set. It can be configured as RV32E, RV32I, RV32IC, RV32IM, or RV32IMC core, and optionally contains a built-in interrupt controller. Tools (gcc, binutils, etc..) can be obtained via the RISC-V Website. The examples bundled with PicoRV32 expect various RV32 toolchains to be installed in /opt/riscv32i[m][c]. See the build instructions below for details.

说明：  基于OV5640摄像头的视频图像传输存储以及读取。供大家参考。(Video image transmission, storage and reading based on ov5640 camera. For your reference.)

USB2.0的IP核开发.代码可以直接使用已经验证过(USB2.0 IP kernel development. Code can be used directly, has been verified)

控制电话信令 完成忙碌 等待 回铃音振铃等(Signaling complete control over telephone ring so busy waiting ringback tone)

基于DE2开发板的VGA显示模块，仅供大家参考(DE2 development board based on the VGA display module, for your reference)

verilog，4、5分频器，5分频器占空比3：2-Verilog, 4,5 dividers, five dividers ratio of 3:2

用VHDL写的4*4乘法器，学习VHDL语言的可以-Use VHDL to write the 4* 4 multiplier, learning VHDL language can be

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：  用于实现上位机与下位机之间通过RS232协议来进行通讯。(It is used to realize communication between upper computer and lower computer through RS232 protocol.)
