  • Patent number: 6633563
    Abstract: A content addressable memory (CAM) having a search field, a mask and an output for each CAM location is used to efficiently determine a processor for processing IP packets, with each IP packet being received as a sequence of cells. IP packets may be assigned to a processor (group) based on an examination of the header data, potentially including IP header and other higher layer protocols headers. The search field of a CAM location is pre-stored with header data, and the bit positions to be searched in the location are specified by using a mask. The output of the location identifies the processor group for executing packets with headers matching the search field, with only the bits specified by the mask being compared. When a first cell of an IP packet is received, the header data is provided as an input to the CAM, and the output identifies the processor (group) for executing the IP packet.

  • Patent number: 6292492
    Abstract: A switch guaranteeing a minimum amount of memory space for desired connection while allowing efficient dynamic change of maximum memory space that can be used by a connection. Only an amount of memory space which is required for guaranteeing the minimum amount of memory space is reserved. When the reserved space is decremented due to new cells being received on connections, the maximum memory space reserved for each connection is dynamically increased. For multicast connections, only a single copy of the cell data is stored even though a multicast cell is transmitted on several ports. Multicast cells can also be processed using the same signals used for processing unicast cells.

  • Patent number: 5905885
    Abstract: A peripheral interface system and apparatus including a pair of integrated circuits, referred to as a system adapter and a socket controller, use a communication protocol, referred to as a windowed-interchip-communication protocol, to interface peripherals, such as PCMCIA cards or infrared devices, and other subsystems having different formats with a CPU system bus. The system adapter communicates to a hard disk drive subsystem using the ATA communication standards to interface an ATA hard disk drive with the CPU system bus. Communication between the system adapter and the socket controller, which communicates with PCMCIA peripheral cards and IR peripherals, is accomplished using the windowed-interchip-communication protocol which may share hardware resources with other communication protocols. Communication between the system adapter and the hard disk drive and between the system adapter and the socket controller may be provided on the same chain of a standard 40 signal ribbon cable.
