Abstract
Described embodiments provide a packet classifier for a network processor that generates tasks corresponding to each received packet. The packet classifier includes a scheduler to generate threads of contexts corresponding to tasks received by the packet classifier from a plurality of processing modules of the network processor. A multi-thread instruction engine processes instructions corresponding to threads received from the scheduler. The multi-thread instruction engine executes instructions by fetching an instruction of the thread from an instruction memory of the packet classifier and determining whether a breakpoint mode of the network processor is enabled. If the breakpoint mode is enabled, and breakpoint indicator of the fetched instruction is set, the packet classifier enters a breakpoint mode. Otherwise, if the breakpoint indicator of the fetched instruction is not set, the multi-thread instruction engine executes the fetched instruction.
