ABSTRACT:
An integrated multiport switch (IMS) in which one combinational logic and register arrangement is provided for executing similar media access control (MAC) functions for a plurality of switch ports. The current access state at each of a plurality of switch ports is maintained at a single state storage location, whereby access of a stored port MAC state and update thereof is simplified. Access to state storage in coordination with the single common combinational logic and register arrangement enables MAC functions for each of the plurality of ports to be performed on a time shared basis to maximize efficiency of use of chip resources and architecture space.
