Adders, Subtractors, and Multipliers - DE2-115

自动售货机，根据所要的东西，自动收费，并进行找零(Vending machine, according to what you want to automatically charge and conduct Keep the change)

说明：  实现电子密码锁的各项功能,经过编译和仿真(Electronic code lock of the function, the compiler and simulation)

上/下计数器是有用的大规模集成

说明：  2018全国大学生FPGA创新设计大赛南京总决赛封闭测试题目，以及自己编写的verilog和testbench，欢迎学习借鉴(The closed test topic of the 2018 National Undergraduate FPGA innovation design competition Nanjing finals, as well as Verilog and testbench compiled by ourselves, are welcome to learn)

说明：  access must be conf urr arr

自己写的一个使用单片机配置FPGA的下位机C代码，使用一个C8051F330,外置SPI FLASH,通过串口可将程序写入FLASH,上电时自动加载到FPGA完成配置。(Wrote it myself, using a microcontroller to configure FPGA code for the next bit plane C, using a C8051F330, external SPI FLASH, the program is written through the serial port can be FLASH, power-on automatically loaded into the FPGA to complete the configuration.)

直接频率合成，Quicklogic提供,部分源文件是Quicklogic 专用文件-direct frequency synthesis, pioneered provide some source document is dedicated ESP

主要介绍，I2C总线主设备发送数据给从设备，代码实现是用Verilog语言实现的，对硬件设计者有很大好处(Introduces, I2C bus master to send data to the slave device, code is implemented in Verilog language, the hardware designer of great benefit)

自己完成的项目，成功用vhdl语言实现数字跑表，可存储。

FPGA与DSP的EMIF通信，EMIF的RAM这方面相应的程序(FPGA and DSP EMIF communication)
