Abstract


Embedded systems are built into the inside of the product for a particular application , a collection of computer hardware and software systems for control , management , communications and other functions . With the advent of the post-PC era , the development in the field of consumer electronics is more robust , powerful data processing capabilities of the ARM processor , extremely complex , so that the information indicates a more intelligent and humane . The image and audio media performance is the main highlight of an embedded product , the primary means of human access to information . Embedded audio and video systems to build an embedded product is extremely important to enhance system performance and functionality is very significant . Further improvements based on previous studies in our laboratory the results of computer music , and improve the intelligent digital voice electronic musical instruments , improved from the soft hardware to start using ARM processor combined μC/OS- Ⅱ embedded real-time operating system , to enhance the overall performance of the system . Developed to study the application of ARM Embedded System , not only for the above applications , but also for the development of a universal the ARM embedded audio and video system , so that it can be more widely used . Of this thesis is to provide a reliable hardware and software development platform to study how to build a complete performance ARM embedded systems for intelligent digital voice-activated electronic musical instruments . The paper first describes the background of the development of embedded audio and video systems , and computer music knowledge and subsequent functional analysis and overall design, analysis, design, embedded audio and video system design of key issues, including the framework of the system development process and development principles embedded processor and operating system choice , the system design of ARM-based embedded applications have universal significance . Then focuses on the design of ARM-based embedded hardware platform , μC/OS- II real-time operating system transplant , BootLoader , the development process of applications based on the real-time operating system μC/OS- Ⅱ . Finally, to summarize the main research work , combined with the development of the advanced technology in today's embedded development platform prospect .
