摘要
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 cQmmon 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.
