Abstract: A booting technology for a multi-die and multi-core computing platform is shown. A storage device stores number 1 firmware code and number 0 firmware code. A master die is coupled to the storage device through a bus and accesses the number 1 firmware code from the storage device through the bus. A first slave die is also coupled to the storage device through the bus. However, instead of accessing the storage device for the number 1 firmware code, the first slave die monitors the bus and retrieves the number 1 firmware code, accessed by the master die, from the bus. The master die further accesses the number 0 firmware code from the storage device through the bus. The master die executes the number 0 firmware code to operate the master die and the first slave die to boot the system and start up the platform.

Abstract: For routing a data unit through a chain of nodes, the nodes are assigned addresses that are increasing in one direction of appearance of the nodes in the chain. For routing the data unit, the receiving node first verifies if the destination address of the data unit corresponds with the address of its first hop neighbor or its second hop neighbor, and the node routes the data unit directly to its first hop neighbor or its second hop neighbor if this is the case. Otherwise, the node determines the difference between the destination address of the data unit and its own address or the difference between the source and destination address of the data unit, selects a routing direction depending on the sign of this difference, and selects a first hop link when the difference is in magnitude below a threshold value or a second hop link when the difference is above the threshold value.
