A System's Construction Of Sound And Video Based On ARM And μCOS-Ⅱ

The embedded system is a computer software and hardware system's aggregates on a special application,which realizes control, management and correspondence function and so on inside the product. After the PC time's arrival,it is stronger in the expense electron domain's development,which uses ARM processor's formidable data-handling capacity and can realize very complex function and causes information expression more intellectualized and user-friendly.The sound and video media's performance is an embedded product main luminescent spot,is a principal means of humanity gaining the information.So it is important that the embedded sound video system is constructed in an embedded product and is obviously to the system's performance and function promotion.According to the achievement of studying the computer-generated music,the laboratory improves and enhances the intelligent digitization voice control electrophone,improves the software and hardware,to use the ARM processor,unifies COS-ⅡEmbedded real-time operating system, lift system's overall performance.When developing ARM embedded system's application,it is not only applies for above but also to develop a section of ARM embedded sound and video system which can obtain a more widespread application.The paper mainly provides a reliable software and hardware development platform for the intelligent digitization voice control electrophone,and searches how to construct one completely,the performance fine ARM embedded system.The paper first introduced the embedded sound and video system's development background,as well as the related computer-generated music knowledge,and then carries on the functional analysis and the system designing,and analyzes the embedded sound and video system design crucial question,including the system frame's design,the development flow and the development principle as well as regarding the embedded processor and operating system's choice, which have the universal significance to embedded application system designing based on ARM.Afterward the paper elaborates mainly embedded hardware platform designing based on ARM,μCOS-ⅡReal-time operating system's transplant,BootLoader,and application procedure performance history based onμCOS-Ⅱreal-time operating system.Finally,it summarizes this paper's main research work, and unifies the embedded vanguard technology development to make the forecast to the platform.
