| Abstract: | The structure and principle of an external data receiving and storing system for wireless capsule endoscope based on CompactFlash Card are introduced in the paper. The system synchronizes the analog image frames receiving and caches the high rate data flow into the FIFO before writing them into CF card under the control of FPGA and MCU during the hibernation time slot. The innovative architecture introduces implements the function of long-time data recording,also with the improvement of reliability of the system. |
