    摘要: A method is provided for address mapping in a network processor. The method includes the steps of (1) determining a port number of a port that receives a data cell; (2) determining a virtual path identifier and a virtual channel identifier for the data cell; and (3) creating a first index based on at least one of the port number, the virtual path identifier and the virtual channel identifier. The method further includes (1) accessing one of a plurality of entries stored in a first on-chip memory using the first index; (2) creating a second index based on the accessed entry of the first on-chip memory; and (3) accessing an entry of a second memory based on the second index. Numerous other aspects are provided.

    摘要: In a first aspect, a method for maintaining control structure coherency is provided. The method includes the steps of (1) writing a pointer to a control structure in a hardware update list while one or more portions of the control structure are accessed by hardware during a hardware update operation; and (2) delaying a software access to one or more portions of the control structure during a software update operation while the pointer to the control structure is on the hardware update list. Numerous other aspects are provided.
