Abstract
In an integrated circuit, a data traffic router includes a number of multiplexors coupled to each other, and to subsystems of the IC. The subsystems selectively output to each other. The data traffic router selectively provides paths for the outputs to reach their destinations, to facilitate concurrent communications between at least two selected combinations of the subsystems.
Claims17
A data traffic router for use in an integrated circuit (IC) to interface a plurality of subsystems of said IC, the data traffic router comprising:
- a first multiplexor coupled to a first, a second and a third subsystem of said IC to select and output for said third subsystem one of a first output of said first subsystem and a second output of said second subsystem;
- a second multiplexor coupled to said first, second and third subsystems of said IC to select and output for said second subsystem one of said first output of said first subsystem and a third output of said third subsystem;
- and
- a third multiplexor coupled to said first second and third subsystems to select and output for said first subsystem one of said second output of said second subsystem and said third output of said third subsystem.
