A node having a node input is configured to receive a plurality of transactions intended for a plurality of different targets. The node has multiple node outputs. At least one target is provided, that target including an input configured to receive a respective output of the node. The node is configured to direct transactions to the at least one target or an output (for passing to a different partition) depending on whether the transactions are intended for the target or a different target. This determination is made in response to a conversion operation which converts a target address of the transaction to an identification associated with the target or the output.

Method and apparatus for routing transactions through partitions of a system-on-chip

A package includes a die and at least one further die. The die has an interface configured to receive a transaction request from the further die via an interconnect and to transmit a response to the transaction request to said further die via the interconnect. The die also has mapping circuitry which is configured to receive the transaction request including at least first source identity information, wherein the first source identity information is associated with a source of the transaction request on the further die. The mapping circuitry is configured to modify the transaction request to replace the first source identity information with local source identity information, wherein that local source identity information is associated with the mapping circuitry. The mapping circuitry is configured to modify the received transaction request to provide said first source identity information in a further field.

Method and apparatus for interfacing multiple dies with mapping to modify source identity

A package includes a die and at least one further die. The die has an interface configured to receive a transaction request from the further die via an interconnect and to transmit a response to the transaction request to said further die via the interconnect. The die also has mapping circuitry which is configured to allocate to the received transaction a local source identity information as source identity information, the local source identity information comprising one of a set of reusable local source identity information. This ensures the order of transactions tagged with a same original source identity and target and allows transactions tagged with different source identifiers to be processed out of order.
