Abstract :
Data-recording device for aircraft requires high-speed, high-capacity and non-volatile storage. In the paper, we provide a good solution for high-speed large-capacity data logger. We use FPGA as controller, SDRAM as high-speed data buffer, CF card as a non-volatile data memory and USB2.0 as Communication interface to design a dual-channel data logger. The Test results show that the recorder sampling rate is 120MSa/s, single-channel data store rate is 38MB/s, the total capacity is 64GB, and data upload rate is up to 30MB/s. Therefore it meets the expectations.
