目前,在数字交换机中大多采用位片器件或高速乘法累加器等来实现对记发器多频信号的接收。本文对采用先进的数字信号处理器TMS32010实现多频接收器的电路进行了介绍.该电路采用两个存贮器作为32010的数据输入接口,两个存储器以轮流方式进行读写操作,接收器时信号的接收按先暂存后处理的方式进行。在这种情况下,32010的优异功能得到了充分发挥,话路复用度达到16。实践证明,采用TMS32010时,接收器的设计及实现均比较简单、灵活,并且体积小、(?)价低。

Currently, digital switches are mostly used bit slice devices or high-speed multiply accumulator, etc. to achieve the receiver multi-frequency signal reception. This article describes the use of advanced digital signal processor TMS32010 multi-frequency receiver circuit is introduced.The circuit uses two memory as the 32010 data input interface, two memories to read and write operations in turn, the receiver The signal received by the first temporary post-processing methods. In this case, 32010’s excellent features have been fully played, the session reuse rate of 16. Practice has proved that the use of TMS32010, the receiver design and implementation are relatively simple, flexible, and small size, (?) Low price.
