| Abstract: | In this paper,a kind of composition mechanism and stored technology of high speed and large-capacity solid state memory are introduced.It takes the field programmable gate array as its logical control unit to acquire image data from the infrared camera by LVDS interface circuit ,and these data will be seamless and real-time stored through pingpong structure.Using the pipeling technology to write Flash can improve the speed of Flash page program,and this system can meet the requirements of larger capacity and higher speed by extending the Flash array.It also can read data from Flash by USB 2.0 interface which controlled by FT245 and upload these data to computer,and the clear results can be got through the analysis software.The results show that this system can store more image data with higher speed steadily and reliably,thus it has stronger feasibility and practicality. |
