摘　　要：话音业务是卫星通信中的重要业务,设计了一种采用多处理器结构的多路话音编解码器,利用多个处理器协作处理,可以实现卫通网中多路话音通信的信令交互以及数据的压缩处理,并通过主机接口(HOST PORT ITERFACE,HPI)和地址/数据(A/D)总线接口解决了多处理器间的数据交互问题。测试结果表明,该方案设计合理,满足系统使用需求。The voice service is one of the most important applications in satellite communication. We put forward the proposal that uses multi-processor structure to design the multi-channel voice system. The system is designed by using several professors. It can resolve the signal processing and the voice data transfer. We use HPI interface and A/D interface to meet the data transfer among the several professors. The prototype test results show that this design scheme is reasonable and can meet the requirements of system applications.
