DSP 实时语音存储系统，将数据存储到 USB 移动存储设备的过程中，存在存储速率快慢不均的现象。采用常用的双缓冲区模式的存储方法，会存在样点丢失的问题。针对上述问题设计一种多缓冲区模式的存储方法。该方法应用于 USB 实时语音采集、存储系统中，解决了样点丢失的问题，保证了存储数据的准确性和完整性。多缓冲区模式的存储方法对其它高速实时数据采集、存储系统具有借鉴作用。

DSP real-time speech storage system stores the data to removable USB storage devices.In storing process there exits the uneven storage rate.If the common double-buffer mode storage method is used,then the problem of sample points’loss will exist.We design a storage method with multi-buffer mode for the above problems.Applying the method to USB real-time speech data acquisition and storage system,it solves the problem of sample points’loss and ensures the accuracy and integrity of the stored data.Multi-buffer mode storage method has the role of reference for other high-speed real-time data acquisition and storage systems.
