摘要： Data is protected using locks, with the protected data sometimes being included in the locking messages, which may reduce overall processing latency, and/or reduce a bandwidth requirement for and/or number of storage operations accessing the native storage of the protected data. For example, the lock manager receives lock requests from each of the requesters, and selectively grants the lock requests. The protected data is typically communicated in the locking messages when the lock is highly contested, or at least two request for access to the data are pending. The lock manager initiates the sequence by indicating in a grant message to a requester to include the protected data in its release message. The lock manager then copies this data received in the release message to its grant message to the next requestor. If no other requesters are waiting, the grant message includes an indication not to send the protected data, and thus the requestor typically stores this protected data to storage so it can be accessed in the future.

摘要： A resource interconnect architecture and associated descriptor protocol provides more efficient communication between different resources in a data processing system. One embodiment uses a backdoor interconnect that allows some resources to communicate without using a central resource interconnect. Another embodiment uses nested descriptors that allow operations by different resources to be chained together without having to communicate back to an originating descriptor resource. In another embodiment, the descriptors are generated in hardware or in software. Other embodiments assign priority or privilege values to the descriptors that optimize processing and error handling performance.

摘要： Sequences of items may be maintained using ordered locks. These items may correspond to anything, but using ordered locks to maintain sequences of packets may be particularly useful. One implementation uses a locking request, acceptance, and release protocol. One implementation associates instructions with locking requests such that when a lock is acquired, the locking mechanism executes or causes to be executed the associated instructions as an acceptance request of the lock is implied by the association of instructions (or may be explicitly requested). In some applications, the ordering of the entire sequence of packets is not required to be preserved, but rather only among certain sub-sequences of the entire sequence of items, which can be accomplished by converting an initial root ordered lock (maintaining the sequence of the entire stream of items) to various other locks (each maintaining a sequence of different sub-streams of items).

摘要： A network processor has numerous novel features including a multi-threaded processor array, a multi-pass processing model, and Global Packet Memory (GPM) with hardware managed packet storage. These unique features allow the network processor to perform high-touch packet processing at high data rates. The packet processor can also be coded using a stack-based high-level programming language, such as C or C++. This allows quicker and higher quality porting of software features into the network processor. Processor performance also does not severely drop off when additional processing features are added. For example, packets can be more intelligently processed by assigning processing elements to different bounded duration arrival processing tasks and variable duration main processing tasks. A recirculation path moves packets between the different arrival and main processing tasks. Other novel hardware features include a hardware architecture that efficiently intermixes co-processor operations with multi-threaded processing operations and improved cache affinity.

摘要： Sequences of items may be maintained using ordered locks. These items may correspond to anything, but using ordered locks to maintain sequences of packets, especially for maintaining requisite packet orderings when distributing packets to be processed to different packet processing engines, may be particularly useful. For example, in response to a particular packet processing engine completing processing of a particular packet, a gather instruction is attached to the particular identifier of a particular ordered lock associated with the particular packet. If no longer needed for further processing, the packet processing engine is immediately released to be able to process another packet or perform another function. The gather instruction is performed in response to the particular ordered lock being acquired by the particular identifier, with the gather instruction causing the processed particular packet to be sent.
