Abstract
A method and system to arbitrate requests of a plurality of ports of an interconnect device are provided. Every port receives combined pending request data that includes a pending request indicator associated with each of the plurality of ports. Each pending request indicator specifies whether a corresponding port has a pending request that needs to be submitted to a request bus of the interconnect device. Further, at each port, a turn to submit a request to the request bus is allocated to one of the plurality of ports based on the combined pending request data, a set of values stored in a mask register and a priority scheme associated with the plurality of ports.
