| Abstract: | In high speed image acquisition,there are huge data to be collected in real-time.This paper proposes a design of high speed real-time image storage system which controlled hard disk directly through FPGA,store real-time data into IDE hard disk in a high speed and access the stored images on PC.At present when one IDE hard disk are used the record speed has attained 24MB/s. |
