【摘要】 在网络多媒体时代,能对大量的多媒体信息进行实时处理的便携式或者嵌入式设备得到了各领域的高度重视。数字信号处理器(DSP)因其具有的高效数字处理能力,在多媒体信号处理和实时设备中获得了大量应用。在多媒体信号处理中同时存在着大容量数据的存储问题。本论文设计实现了基于DSP平台的嵌入式文件系统,从而可以使DSP支持目前通用的大容量存储介质,如IDE硬盘或USB硬盘等,极大的增强了DSP系统的文件访问能力和存储能力。更多还原

【Abstract】 In the multi-media network era, it’s useful and important to design some portable and/or embedded systems, which can process the mass information contained in the multimedia signal. Because of its high efficiency in digital computation, Digital Signal Processor (DSP) has been widely used in multi-media signal processing and real-time systems. But in multimedia signal processing there are so many datum that should be saved and up to now there isn’t a general file system based on DSP platform that will be the obstacle for DSP application. In this papers an embedded file system based on DSP platform is introduced, which will facilitate the DSP to access the massive storage devices, such as IDE/USB hard disk.更多还原
