Abstract
In accordance with embodiments disclosed herein are mechanisms for enabling multiple bus master engines to share the same request channel to a pipelined backbone including: receiving a plurality of unarbitrated grant requests at an agent bus interface from a plurality of masters, each requesting access to a backbone connected via a common request channel; determining which of the unarbitrated grant requests is to issue first as a final grant request; storing a master identifier code for the final grant request into a FIFO buffer, the master identifier code associating the final grant request with the issuing master among the plurality of masters; waiting for a backbone grant; and presenting the master identifier code for the final grant request to an agent bus interface, wherein the agent bus interface communicates a command and data for processing via a backbone responsive to the backbone grant to fulfill the final grant request.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
