As a device for collecting, storing and replaying signal data, the pre-demodulation digital recorder is used in the field of aerospace widely. In this article, we clarified the software development experience of the pre-demodulation digital recorder with high bandwidth, large storage and reliability based on Rtlinux and XFS. RTlinux can respond to the hardware interrupt promptly£¨so data collecting is almost in real time. At the same time£¨ we select XFS to manage very large data files, and RAID to guarantee the reliability of the data stored. The RTFIFO and MBUFF in RTLinux provide communications interface for kernel procedures and user space. This is a successful case of RTLinux application.
