摘要
随着实时语音数据采集系统的不断发展,将数据以某种常用文件系统的形式保存在外存中的方法也得到了越来越广泛的使用,为了使系统满足实时系统的要求,需要对它的性能进行相应的改进。该文基于LPC2210和CF卡,实现了以FAT16为文件格式的实时语音采集系统,并且,为了满足实时系统的需要从缓冲区设计和系统操作等方面进行改进。
With the continuous development of real-time voice acquisition systems,to sotre the data in the storage in format of a usual file system has been widely used.In order to meet the requirements of the real-time system,it is necessary to improve the performance of the system Based on LPC2210 and CF card,this paper implements a real-time voice acquisition system based on FAT16,and improves the performance from the aspects of the buffer design and the system operation.
