On-die functional blocks may use multiple communication networks to send requests and receive responses. For example, a first functional block may send a request via a first network. In response to receiving the request, a second functional block may respond to the first functional block via a second network. The second functional block may also send any requested data to the first functional block via a third network.

Multiple on-die communication networks

A method for communication among multiple on-die functional blocks using multiple communication networks is disclosed. The method may include sending a request from a first functional block via a first network. In response to receiving the request, a second functional block may respond to the first functional block via a second network. The second functional block may also send any requested data to the first functional block via a third network.

A method for removal of an offlining cache agent, including: initiating an offlining of the offlining cache agent from communicating with a plurality of participating cache agents while a first transaction is in progress; setting, based on initiating the offlining, an ignore response indicator corresponding to the offlining cache agent on each of the plurality of participating cache agents; offlining, based on setting the ignore response indicator, the offlining cache agent; and ignoring, based on setting the ignore response indicator, a first response to the transaction from the offlining cache agent.

Method and system for removal of a cache agent

An integrated circuit (IC) having an on-die data network is disclosed. The IC includes a first bus and second buses configured to convey signals in first and second directions, respectively, along a first axis. The second direction is opposite the first. The IC further includes third and fourth buses configured to convey signals in third and fourth directions, respectively, along a second axis perpendicular to the first axis. The fourth direction is opposite the third. Each bus is N-bits wide and unidirectional. Signal lines of two different buses having equal bit significance and opposite direction are arranged adjacent to one another. A crossbar unit having N crossbar switching circuits is configured to couple signal lines of a selected one of the buses to a corresponding signal line of another selected one of the buses. The signal lines of the buses are implemented on different metal layers than the crossbar switching circuits.
