Mass TDMA complex switching chip data processing method

Abstract

The method thereof comprises: in TDM chip, a series / parallel converter converts the series TDM bit-stream into the parallel data in an 8 bits bit-wide; the input memory implements the buffering / bit-wide conversion for the data, namely converting the parallel data in 8 bits bit-wide into the parallel data in 8*m bit-wide; the parallel / series converter converts the parallel data in 8 bits bit-wide into the TDM bit-stream; the output memory implements the buffering / bit-wide conversion, namely converting the parallel data in 8*m bit-wide into the parallel data in 8 bits bit-wide, and implements relevant TDM switch.

Description

technical field

[0001] The invention relates to a communication system data exchange element, in particular to a data processing method of a large-capacity time-division multiplexing exchange chip. Background technique

[0002] TDM (Time Division Multiplexing) has been widely used in existing modern communication systems. The functional block diagram of the existing TDM switching chip is shown in Figure 1. The input TDM signal is written into the input memory after the serial / parallel conversion of the serial / parallel converter; the switching module is based on the configuration data read from the switching table memory. The data read from the input memory is written into the corresponding address of the output memory to complete the TDM exchange; the data read from the output memory becomes the output TDM signal after the parallel / serial conversion of the parallel / serial converter.

[0003] The design scheme of the TDM switching chip in the above-mentioned prior art can we...
