Abstract
There is disclosed a data processor having a clustered architecture that comprises a plurality of clusters and an interrupt and exception controller. Each of the clusters comprises an instruction execution pipeline having N processing stages. Each of the N processing stages is capable of performing at least one of a plurality of execution steps associated with instructions being executed by the clusters. The interrupt and exception controller operates to (i) detect an exception condition associated with one of the executing instructions, wherein this executing instruction issued at time t , and (ii) generate an exception in response to the exception condition upon completed execution of earlier ones of the executing instructions, these earlier executing instructions issued at time preceding t .
