    摘要： A spark plug which includes a center electrode metal shell and an insulator disposed therebetween utilizes for the insulator or ceramic with improved high temperature electrical properties which includes alumina in an amount between about 90 and about 99% by weight, a zirconium containing compound in an amount between about 0 and about 1% by weight, and an oxide mixture in an amount between about 1 and about 10% by weight. The oxide mixture includes a glass former, a network modifier and alumina in an amount between about 16% and about 40% by weight after firing, wherein the molar ratio of the glass former to the network modifier ranges between about 0.8:1 and 1.2:1. The ceramic insulator is particularly adapted for use as an insulator in a spark plug to provide improved dielectric strength and shunt resistance of greater than one 1000 megaohms at 1000 degrees Fahrenheit, so as to reduce the shunting of the spark plug and thereby improve the quality of the spark generated by the spark plug.

    摘要： A network communication device including port control circuitry for controlling packet flow between the ports of the device, where the port control circuitry includes a port manager that directs packets between the ports and port bonding circuitry that bonds two or more of the ports into a bonded port set. For each packet to be sent via the bonded port set, the port bonding circuitry selects one of the bonded ports for transmitting the packet. More than one bonded port set may be defined in a given communication device, and each bonded port set may include from two ports up to all the ports of the device, as long as each port is included in only one bonded port set. One or more port bonding registers are provided to identify which of the plurality of ports are bonded in each bonded port set. In one embodiment, the bonded ports are selected on a packet by packet basis so as to achieve a relatively even distribution of packets sent by each bonded port. In an alternative embodiment bonded ports are assigned to packet source identifiers so as to achieve a relatively even distribution of source identifiers among the bonded ports. If bonded ports are assigned to particular source identifiers, then the traffic is preferably monitored and the assignments are periodically adjusted to achieve even distribution of packet flow on the bonded link. The bonded ports may have different bandwidths, in which case traffic is distributed on a proportionate basis.

    摘要： A pinless connector interposer for making densely populated, inexpensive, simple, reliable, self-wiping connections between components used in semiconductor packaging such as semiconductor carrying substrates, flexible and rigid printed circuit boards and cards. The connector interposer comprises an elastomeric base member in which deformable protrusions are formed on both the top and bottom surface of the base member, wherein the protrusions correspond to contact pads of semiconductor packaging components. An electrically conductive metal coated flexible overlay is bonded to the base member, forming electrically conductive tab elements, enabling a multitude of connections to be made to a semiconductor package. The connections can be accommodated on centers as low as 0.025 inches, despite the non-planarity that may exist between the packaging components of a system.

    摘要： Method and apparatus for improving processor performance. In some embodiments, processing speed may be improved by reusing data stored in a buffer during an initial request by subsequent requests. Assignment of temporary storage buffers in a controller may be made to allow for the potential for reuse of the data. Further, a hot buffer may be designated to allow for reuse of the data stored in the hot buffer. On subsequent requests, data stored in the hot buffer may be sent to a requesting device without re-retrieving the data from memory.

    摘要： A system and technique for detecting data errors in a memory device. More specifically, data errors in a memory device are detected by initiating an internal READ command or cleansing operation from a set of logic which is internal to the memory system in which the memory devices reside. Rather than relying on a READ command to be issued from an external device, via a host controller, the cleansing logic initiates a cleansing routine in response to an event such as an operator instruction or a periodic schedule. By implementing the cleansing operation, the system does not rely on external READ commands to verify data integrity. Further, a monitoring device is coupled between the cleansing logic and a memory scheduler. The monitoring device provides a feed back mechanism from which to vary the frequency of certain memory requests such as the cleansing and scrubbing operations. The cleansing routine may rely on typical ECC error logging mechanisms and may be used in a RAID memory architecture. Further, the cleansing routine may be used in conjunction with other error logging and correction logic, as well as scrubbing logic.

    摘要： A network switch including one or more network ports for receiving and transmitting data is disclosed. The network switch also includes a processor, a switch manager, and memory. Each port includes a network interface, a data bus interface, and a processor port interface. A data bus is coupled to the data bus interface of each of the ports and the switch manager. A processor bus is coupled to a processor, the switch manager, and to the processor port interface of each of the ports. A memory bus is coupled to the memory and the switch manager. The switch manager periodically polls each of the network ports to determine the status of each port. The switch manager controls the flow of data between the network ports and memory based on the port status. The separate processor bus allows the processor to perform overhead functions, such as monitoring, determining status and configuration, without consuming valuable data bus bandwidth.

    摘要： A network switch including a central memory that stores device identification information, port numbers, control information, and packet data received at the ports of the switch. The memory includes a packet section that stores packet data and a device identification section that stores identification entries, where each entry corresponds to a network device coupled to a port of the switch. The switch includes a switch manager to control data flow between the ports and the central memory. Each of the identification entries includes a unique network address to identify one of the network devices and a port number to identify one of the network ports. Each of the identification entries is located within the central memory at a hash address derived by hashing the unique network address. Hash logic receives and hashes each network address to determine a hash address, which is used to access the identification entries. The memory is organized into a chain structure to enable quick access of entries. The switch manager further includes a control memory for storing control registers, including a freepool control register for identifying a freepool chain of memory sectors, a receive control register for identifying a corresponding receive sector chain and a transmit control register for identifying a corresponding transmit packet chain for each of the ports.

    摘要： A network switch including a plurality of first network ports, a plurality of second network ports, a first bus, a second bus and a bridge interface coupled between the first and second buses. The first ports receive and transmit network data according to a first network protocol and the second ports receive and transmit network data according to a second network protocol. The first and second buses operate according to different bus standards. The bridge interface enables data transfer between the first and second buses and thus between the networks operating at different protocols. The switch includes a switch manager that controls the flow of network data and a processor for performing supervisory and control functions. The bridge interface includes receive buffers and transmit buffers assigned to respective ports. During packet data transfer operations across the first bus, the bridge interface emulates a first network port. During packet data transfer operations across the second bus, the bridge interface primarily acts as a slave to the second network ports by storing control lists for execution by the second network ports. This processor is relieved of performing necessary overhead functions associated with the second bus and is thus freed to perform other important switch functions.
