基于ARM+FPGA嵌入式便携型文档播放器的设计

Design of Portable Office Document Playerembedded System based on ARM+FPGA

设计了一款可以直接解码Microsoft office文件(Word,Excel,PowerPoint)、Adobe PDF文件和图片文件(BMP,JPG,GIF),并且将文件的内容转换成VGA视频输出的嵌入式便携型播放器。在设计中,还利用FPGA芯片,成功地实现了包括Bayer抖动进行图像增强以及简单插值实现帧速提升、USB接口扩展和高速设备检测方面的技术运用与改进。

In this paper,we design a portable Microsoft Office documents（Word,Excel,PowerPoint）,Adobe PDF files and pictures files（BMP,JPG,GIF） player which can directly convert the content of files into VGA video output.In this project,we achieve three kinds of function by using FPGA,including extending the USB interface and detecting the USB device,image enhancing with Bayer dithering algorithm and increasing the frame rate by simple interpolation.
