摘要： Systems and methods for implementing counters in a network processor with cost effective memory are disclosed. Embodiments include systems and methods for implementing counters in a network processor using less expensive memory such as DRAM. A network processor receives packets and implements accounting functions including counting packets in each of a plurality of flow queues. Embodiments include a counter controller that may increment counter values more than once during a R-M-W cycle. Each time a counter controller receives a request to update a counter during a R-M-W cycle that has been initiated for the counter, the counter controller increments the counter value received from memory. The incremented value is written to memory during the write cycle of the R-M-W cycle. A write disable unit disables writes that would otherwise occur during R-M-W cycles initiated for the counter during the earlier initiated R-M-W cycle.

摘要： A method and structure for determining when a frame of information comprised of one or more buffers of data being transmitted in a network processor has completed transmission is provided. The network processor includes several control blocks, one for each data buffer, each containing control information linking one buffer to another. Each control block has a last bit feature which is a single bit settable to “one” or “zero” and indicates when the data buffer having the last bit is transmitted. The last bit is in a first position when an additional data buffer is to be chained to a previous data buffer indicating an additional data buffer is to be transmitted and a second position when no additional data buffer is to be chained to a previous data buffer. The position of the last bit is communicated to the network processor indicating the ending of a particular frame.

摘要： A Network Processor includes a Fat Pipe Port and a memory sub-system that provides sufficient data to satisfy the Bandwidth requirements of the Fat Pipe Port. The memory sub-system includes a plurality of DDR DRAMs controlled so that data is extracted from one DDR DRAM or simultaneously from a plurality of the DDR DRAMs. By controlling the DDR DRAMs so that the outputs provide data serially or in parallel, the data Bandwidth is adjustable over a wide range. Similarly, data is written serially into one DDR DRAM or simultaneously into multiple DDR DRAMs. As a consequence buffers with data from the same frame are written into or read from different DDR DRAMs.

摘要： A method and system for reducing memory accesses by inserting qualifiers in control blocks. In one embodiment, a system comprises a processor configured to process frames of data. The processor may comprise a plurality of buffers configured to store frames of data where each frame of data may be associated with a frame control block. Each frame control block associated with a frame of data may be associated with one or more buffer control blocks. Each control block, e.g., frame control block, buffer control block, may comprise one or more qualifier fields that comprise information unrelated to the current control block. Instead, qualifiers may comprise information related to an another control block. The last frame control block in a queue as well as the last buffer control block associated with a frame control block may comprise fields with no information thereby reducing memory accesses to access information in those fields.

摘要： Data structures, a method, and an associated transmission system for multicast transmission on network processors in order both to minimize multicast transmission memory requirements and to account for port performance discrepancies. Frame data for multicast transmission on a network processor is read into buffers to which are associated various control structures and a reference frame. The reference frame and the associated control structures permit multicast targets to be serviced without creating multiple copies of the frame. Furthermore this same reference frame and control structures allow buffers allocated for each multicast target to be returned to the free buffer queue without waiting until all multicast transmissions are complete.
