基于FPGA的嵌入式系统设计
摘要
本文设计完成的是基于FPGA的嵌入式系统开发板,它可以完成FPGA、嵌入式系统和SOPC等的设计和开发。
开发板以Altera公司的Cyclone系列FPGA—EP1C6为核心,在其外围扩展FLASH、SRAM、A/D、D/A、键盘、LED显示、LCD显示、串口通信、VGA接口、PS2接口和USB接口等器件,使其成为一个完整的嵌入式开发系统,系统采用模块化设计,各个模块之间可以自由组合,使得该开发板的灵活性和可扩展性大大提高。同时开发板所提供的丰富的接口模块,供人机交互和器件间通信使用,方便了开发者的设计和系统的嵌入,可以满足普通高等院校、科研人员等的需求。
开发者可以使用VHDL语言、Verilog HDL语言、原理图输入等多种方式进行逻辑电路和功能模块设计,也可以利用Altera公司提供的IP资源和Nios 16/32位处理器开发嵌入式系统,借助QuartusII和Nios SDK Shell软件进行编译、下载,并通过本嵌入式系统开发板进行调式和结果验证。

ABSTRACT
The pletes a design of an embedded system development board based on development board plete the design of FPGA,embeded system,SOPC and so on.
The development board is based on Altera Cyclone device—EP1C6,the board extends several peripheral devices such as,FLASH,SRAM,
A/D,D/A,LED,LCD,keyboard,serial port,VGA interface,PS2 interface,
USB interface and so the devices constitute an integrated embeded development system. The development board offers us plenty of interfaces to meet the need of the munication and the munion between human puter,which makes the design and the embedding of the system more Nios Development Board can meet the need of scientific researchers and other college researchers.
The developers can use VHDL,Verilog HDL,schematic input mode and so on to design logic circuit and function block,they can alse use the IP core and Nios microprocessor which are offered by Altera to develop embedded systems. The developers can utilize QuartusⅡ and Nios SDK Shell pile and download,then they can use this development board to debug and validate the result.
KEY WORDS: embeded system, Nios embeded CPU,SOPC,FPGA
