Abstract
Described embodiments provide a packet classifier of a network processor having a plurality of processing modules. A scheduler generates a thread of contexts for each tasks generated by the network processor corresponding to each received packet. The thread corresponds to an order of instructions applied to the corresponding packet. A multi-thread instruction engine processes the threads of instructions. A function bus interface inspects instructions received from the multi-thread instruction engine for one or more exception conditions. If the function bus interface detects an exception, the function bus interface reports the exception to the scheduler and the multi-thread instruction engine. The scheduler reschedules the thread corresponding to the instruction having the exception for processing in the multi-thread instruction engine. Otherwise, the function bus interface provides the instruction to a corresponding destination processing module of the network processor.
