Abstract: A communications interface on a data path between a plurality of data channels and a single communications port on a processor. The communications interface controls data as it passes on a receive path from the plurality of data channels to the single communications port and on a transmit path from the single communications port to the plurality of data channels and is adapted to use a memory to buffer the data when necessary. The communications interface (i) adds a channel identifier, which identifies to which data channel the data relates, to the data on the receive path so that the processor will be able to determine to which data channel the data relates and (ii) removes a channel identifier from the data on the transmit path so that the data will leave the communications interface in the same format in which it was received.

Abstract translation: 在多个数据信道与处理器上的单个通信端口之间的数据路径上的通信接口。 通信接口控制数据，因为它在从多个数据信道到单个通信端口的接收路径和从单个通信端口到多个数据信道的发送路径上传递数据，并且适于使用存储器来缓冲数据 必要时。 通信接口（i）将识别数据所关联的数据信道的信道标识符添加到接收路径上的数据，使得处理器将能够确定数据与哪个数据信道相关，并且（ii） 来自发送路径上的数据的信道标识符，使得数据将以与其接收的相同格式离开通信接口。
