System architecture and method for communication between devices over backplane to reduce interface count

摘要

The present disclosure discloses a system architecture and method for reducing pin count on a backplane connecting plurality of devices. In an embodiment, the signals from the plurality of devices are multiplexed or mapped into time slots using a MapMux device. The MapMux device then sends the multiplexed or mapped signals over backplane on TDM bus. The MapMux device at the receiving end de-multiplexes or de-maps and sends the received signals to plurality of devices for further processing. The present disclosure allows a large number of signals to be passed between the devices through a single stream.

1. A system architecture for communication of devices over a backplane, comprising:
a plurality of first devices for performing at least one of sending, receiving and processing input signals, wherein the input signals comprise at least one of status signals and control signals; at least one MapMux device connected to the plurality of first devices, a Time Division Multiplexing (TDM) bus and a selection unit, to perform a predetermined functionality based on a select signal obtained from a selection unit, wherein the predetermined functionality includes:
mapping of the input signals obtained from each of the plurality of first devices, to output a first processed data to at least one of other devices over the TDM bus; andde-mapping of an incoming data obtained from at least one of the other devices over the TDM bus.
