Abstract
A method of reconfiguring an addressing mechanism in a system-on-chip comprising system circuitry and monitoring circuitry having tree-structured units for routing communications through the system, includes sending a discovery message, receiving discovery responses from the units, each discovery response identifying the number of individually addressable entities in that unit and those units in the branch above that unit; in response to not receiving a response from one or more units, determining that one of those units is defective; enabling a crosslink between a first unit in the same branch as the defective unit and a second unit in an adjacent branch; sending a further discovery message; receiving a further discovery response from the second unit identifying the number of individually addressable entities in that second unit, those units in the branch above that second unit, the first unit, and those units in the branch above the first unit; and reconfiguring the address of the crosslink so as to cause a subsequent communication to an individually addressable entity in the defective unit's branch to be routed via the adjacent branch and the crosslink, thereby bypassing the defective unit.
