The Implementation Of Hi-Fi Embedded System Based On Linux

As Linux operation system is widely used on the embedded system, Linux is ported to more and more platform and there are more and more applications to be ported to the Linux platform. SH7751R board made by Renesas Technology is a 32-bit high performance microprocessor platform, featuring a built-in PCI bus controller compatible with PCs and multimedia devices.Though the SH7751R board has powerful function and performance, there is no integrated Hi-Fi Audio system based on the platform.Therefore, the paper is just to build a reliable Hi-Fi Audio system based on SH7751R board through PCI bus.The paper analysis the implementation of HI-FI audio system on the embedded Linux platform based on SH7751R boardIn the paper, it has following focuses:At first, it introduces related knowledge about digital audio and Hi-Fi system, and describes something about supporting audio format.Then, it introduces related knowledge about embedded system and makes comparison of several mainstream embedded operation systems according to function and performance, and tell why choose embedded linux operation system.Then, the paper analyzes in detail how to design the Linux Hi-Fi Audio system.Firstly, it brings forward system requirements, and present...
