Design Of Mini System For High-speed Image Storage

For meeting the demand of high-altitude plane and other special occasions, the image storage system should be small size, high-speed storage, low temperature resistance, the common image storage systems on the market can not meet this demand. Through improving the existing image storage systems, the mini system for high-speed image storage was designed. The system chose programmable logic device and ping-pang operation in order to improve storage speed effectively. Through selecting MCU to control, simplifying the existing image storage system, choosing the key device and arranging PCB layout reasonably, the size of the whole system was 100mm×100mm×110mm (W×L×H). At the same time, with the USB interface, digital image can be send to PC to display.Debugging results show that the plan of the system is practicable, and the system was able to complete the image data collection, storage, transmission and display effectively, the speed can reach about 25MByte/s.
