摘要： Systems and methods for implementing multi-frame control blocks in a network processor are disclosed. Embodiments include systems and methods to reduce long latency memory access to less expensive memory such as DRAM. As a network processor in a network receives packets of data, the network processor forms a frame control block for each packet. The frame control block contains a pointer to a memory location where the packet data is stored, and is thereby associated with the packet. The network processor associates a plurality of frame control blocks together in a table control block that is stored in a control store. Each table control block comprises a pointer to a memory location of a next table control block in a chain of table control blocks. Because frame control blocks are stored and accessed in table control blocks, less frequent memory accesses may be needed to keep up with the frame rate of packet transmission.

摘要： Packets or frames of data may be compressed, encrypted/decrypted, filtered, classified, searched or subjected to other deep-packet processing operations before being distributed through the internet. The microprocessor system and method of the present invention provide for the orderly processing of such data packets without disrupting or changing the sequence in which the data is intended to be transmitted to its destination. This is achieved by receiving frames into an input buffer for processing. Associated with this input buffer is a unit for determining the operation to be performed on each frame. An arbitrator assigns each frame to a processing core engine. An output buffer collects the processed frames, and a sequencer forwards the processed frames from the output buffer to their destination in the same order as received by the input/output buffer. Maintaining the sequence of data transmission is particularly useful in voice transmission, such as videos and movies.

摘要： Disclosed is a method and system for validating a data packet by a network processor supporting a first network protocol and a second network protocol and utilizing shared hardware. The network processor receives a data packet; identifies a network packet protocol for the data packet; and processes the data packet according to the network packet protocol comprising: updating a first register with a first partial packet length specific to the first network protocol; updating a second register with a second partial packet length specific to the second network protocol; and updating a third register with a first checksum computed from fields independent of the network protocol. The system produces a second checksum utilizing a function that combines values from the first register, the second register, and the third register. The system validates the data packet by comparing the data packet checksum to the second checksum.

摘要： A method and apparatus for assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. In a given processing period, sinks that are available to receive work are identified and sources qualified to send work to the available sinks are determined taking into account any assignment constraints. A single source is selected from an overlap of the qualified sources and sources having work available. This selection may be made using a hierarchical source scheduler for processing subsets of supported sources simultaneously in parallel. A sink to which work from the selected source may be assigned is selected from available sinks qualified to receive work from the selected source.
