摘要
针对如何利用INIC(Intelligent Network Interface Controller)实现车载MOST25(Media Oriented SystemsTransport)环形网络的问题,在介绍MOST25网络的原理与方法基础上给出了MOST25智能网络中音频播放节点的设计原理及其实现方法。节点设计方案中,网络控制器采用智能网络接口控制器OS81050,解码器采用可控音量芯片CS4341,功率放大器采用NE5532。应用实例表明,设计是有效可行的,并达到了很好的音响效果,具有信号保真度高、易添加或卸载等优点。
In order to solve the problem of using INIC （Intelligent Network Interface Controller） to structure the MOST^25 （Media Oriented Systems Transport） ring network, the theory and the method of MOST^25 network are introduced, and the design of the MOST^25 audio amplifier node and its implementation are provided. In the design of this node, the network controller used the intelligent network interface controller OS81050, the eneoder used CS4341, the amplifier used NE5532. The application example of the design which has achieved a good sound effect is feasible. The results demonstrated that the design is effective and feasible, it has the advantages such as high fidelity, easy to install/uninstall.
