SSI端口的多路语音复用方案设计

Scheme Design for One SSI Port Shared by Multi-Channel Audio Signal

同步串行接口 (SSI)是各类 DSP处理器中的常见接口。工作在网络模式下的SSI端口在某些应用场合非常重要。本文先对工作在网络模式下的 SSI端口的工作原理及特性进行了介绍 ,随后提出了 SSI端口在网络模式下的几种应用方案。

The standard digital interface of CODEC is SSI (Synchronous Serial Interface) port. In some particular application situation, it needs SSI port to operate in network mode. In this paper, the operation principle and characteristics of SSI port in network mode are introduced. Several application schemes of SSI port in network mode are also given.
