US 11,447,071 B2 · Flexible hub for handling multi-sensor data

Abstract

A hub that receives sensor data streams and then distributes the data streams to the various systems that use the sensor data. A demultiplexer (demux) receives the streams, filters out undesired streams and provides desired streams to the proper multiplexer (mux) or muxes of a series of muxes. Each mux combines received streams and provides an output stream to a respective formatter or output block. The formatter or output block is configured based on the destination of the mux output stream, such as an image signal processor, a processor, memory or external transmission. The output block reformats the received stream to a format appropriate for the recipient and then provides the reformatted stream to that recipient.

Dependent claims

A circuit comprising:

a demultiplexer that includes an input and a set of outputs;
a set of multiplexers that each include a set of inputs coupled to the set of outputs of the demultiplexer and further include an output;
and
a demultiplexer table coupled to the demultiplexer, wherein the demultiplexer is operable to:
receive a first data stream that includes a set of virtual channels;
utilize the demultiplexer table to divide the set of virtual channels of the first data stream among the set of outputs of the demultiplexer;
provide a second data stream that includes data of a first subset of the set of virtual channels at a first output of the set of outputs of the demultiplexer;
and
provide a third data stream that includes data of a second subset of the set of virtual channels at a second output of the set of outputs of the demultiplexer.
