基于VHDL的串行同步通信SPI设计

本设计是用Quartus作为开发环境，以DE2板为硬件平台实现的SPI同步串行通讯。设计过程方便。根据接收和发送两个主要部分实现了SPI的基本功能。此外，该设计还实现了波特率发生器，数码管显示的功能。用DE2板实现具有电路简洁，开发周期短的优点。充分利用了EDA设计的优点。开发过程用了VHDL硬件描述语言进行描述，从底层设计，分模块进行，充分提高了设计者的数字逻辑设计的概念。-VHDL-based SPI serial synchronous communication design as the design is the use of Quartus development environment to DE2 board as the hardware platform of the SPI synchronous serial communication. Facilitate the design process. According to both send and receive SPI implements the main part of the basic functions. In addition, the design also implements the baud rate generator, digital display features. DE2 board to achieve a circuit with a simple, short development cycle advantages. Full use of the EDA design advantages. Development Process VHDL hardware descr iption language used to describe the design from the ground, sub-module, to fully enhance the designer' s concept of digital logic design.
