Research On The System For File Storage Media Conversion Processing

File is the past and present national institutions, social organizations and individuals engaged in the political, military, economic, scientific, technical, cultural, religious and other activities to direct the formation of the state and society to save the value of a variety of text, graphics, audio and video different forms of history. Traditional file on paper as a carrier for recording information, a long stored will appear yellowed paper, damaged, illegible, eventually lead to the loss of important files, and with the development of technology and social progress, information management has penetrated into various fields, file storage media transformed from the traditional paper files in to electronic files. An electronic file processing technology also emerged.This paper analyzes the structure and working principle of the digital camera, further points out that the images collected to parallel processors for image processing, which is one of the hot spots. Through the analysis of the structure and working methods of the field programmable gate array (FPGA), pointed out that the application of FPGA devices for image processing, in order to solve the problems of real-time systems, fast advantage. Based the FPGA programmable system-on-chip (SOPC) design flexibility, functionality can be cut, programmability and good integration of the hardware and software aspects of the characteristics of the programmable system-on-chip image processing design ideas and processes.According to the functional characteristics of the File storage medium conversion processing system, of the entire system carried on the reasonable hardware and software divided. In the of this on the basis of have, there are built from Based the overall architecture of the image processing system of the SOPC technology, and the on our image acquisition, image processing, image. Display wait function module carried out a structure design of respectively. The hardware design of the system is carried out in the in the Quartus II development environment, while the software part in the Nios II in the software development environment prepared by the. The acquisition part of the system first analyzes the basic structure and mode of operation of the SD card FAT file system is analyzed, and then read the pictures from the SD card into the FPGA, the image processing section, the first images obtained detection, to see pictures is not tilt, and then in the Nios II in the software development environment the pictures of the write a program on the tilt of the carried out of the rotation correction of the image convert Photo to format at the same time, image display the part of this to directly will the pictures processed by the FPGA control VGA display. Finally, experimental verification of the entire system design, the results show that the system basically meet the expected demand, has some practical reference value.The topic has been hardware and software design and testing, the basic realization of the original design goals. Building a set of FPGA based on file storage media conversion processing system. Provides a reference for future research and laid the foundation.
