摘要
在嵌入式系统应用中,如果能够创建仿真环境,并利用仿真环境的优势进行算法的验证、系统的移植、应用程序的设计,就能够极大地提高开发的灵活性,节省开发资源,验证系统的可行性。文中分析了开放源码的嵌入式系统仿真集成开发环境SkyEye,并实现在该软件平台上基于ARM7TDM I核的AT91EV40仿真开发板的实时操作系统μC/OS-Ⅱ的移植。把语音识别从试验室推广到实际应用中,在嵌入式系统中进行研究是必然的要求。在该嵌入式软硬件仿真平台上实现说话人识别算法的研究,选取改进了配合于硬件的算法,取得了良好的效果。
In the application of embedded system, if we can create an emulational environment and make use of its advantage to test the algorithm, to transplant system , to develop software, we will increase the flexibility of system development, save the resource, validate the feasibility of system. The paper analyzes an open source software SkyEye which is an emulatinal embedded system, and a real -time system μC/OS - Ⅱ is transphanted on AT91EV40 development board which is emulated by SkyEye. The study of speech recognition based on embedded system is the requirement of application. This paper achieved the speaker recognition algorithm on the emulatinal embedded system. By selecting and optimizing the algorithm matching the hardware, the performance was improved a lot.
