Research of Huge Storage Device for Audio Signals Based on Embedded Linux Operating System
Based on the advanced RISC microprocessor (ARM) and embedded Linux operating system, this paper introduces an approach for developing a huge storage device for audio signals. In this paper, a codec is used to acquisition audio signals, and the data is stored in SD card which is controlled by the microprocessor according to the US-bus standard format. The codec driver program is completed in this paper, and the SD card driver program is developed based on Linux operating system and SD card agreement. A special data storage file system is accomplished for reading and writing SD card, as well as managing of the data file by the FATI6 file system.
