Abstract:

 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 encoder 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.

Key words: media oriented systems transport(MOST25), intelligent network interface controller, net services, I2S bus
