摘要： Described embodiments provide address translation for data stored in at least one shared memory of a network processor. A processing module of the network processor generates tasks corresponding to each of a plurality of received packets. A packet classifier generates contexts for each task, each context associated with a thread of instructions to apply to the corresponding packet. A first subset of instructions is stored in a tree memory within the at least one shared memory. A second subset of instructions is stored in a cache within a multi-thread engine of the packet classifier. The multi-thread engine maintains status indicators corresponding to the first and second subsets of instructions within the cache and the tree memory and, based on the status indicators, accesses a lookup table while processing a thread to translate between an instruction number and a physical address of the instruction in the first and second subset of instructions.

摘要： 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.
