中文题目基于FPGA的数码相框制作
英文题目 Design of digital photo frame based on FPGA
中文摘要
FPGA器件的应用是继单片机之后,当今地嵌入式系统开发应用中最最热门的关键技术之一,并且随着制造工艺水平的不断提高,成本的不断下降,FPGA甚至大有替代专用ASIC的趋势。FPGA使用Verilog或VHDL等硬件描述语言编程。本课题是DIY数码相框,是基于FPGA的数码相框设计。本系统工程的所有功能全部使用FPGA来完成,内容包括SD卡的读取控制,图片解码,VGA驱动显示等等,采用的是SF—EP1C开发板,该板FPGA使用Altera公司Cyclone系列的EP1C3T144C8,配置PLL电源电路,SD接口,1个256色的VGA通用接口,SDRAM等。支持AS及JTAG配置方式,软件平台使用Quartus Ⅱ ,从而完成10幅800*600的BMP图片循环显示。

外文摘要
Title Design of digital photo frame based on FPGA

Abstract
The application of FPGA devices is today's one of the most popular key technologies in the development and use of embedded systems after the MCU . and with the level of the manufacturing process constantly improving and the costs continuously declining, the FPGA will have the tendency of even replacing the dedicated ASIC. The FPGA programs use Verilog or VHDL hardware description language. The system plishes all the functions including the reading and controlling of SD card, decoding the pictures , drivering VGA, etc. based on the FPGA, which uses the SF-EP1C development board. The board use EP1C3T144C8 of Altera's Cyclone series as FPGA including the PLL power supply circuit, SD interface, a 256-color mon interface, SDRAM, and so on ,supporting for AS and JTAG configuration. The software pletes displaying ten 800 * 600 BMP picturess in cycles by using the Quartus II .
