摘要： Methods and apparatus for reducing the average delay associated with sending a packet from one environment to another via a store and forward buffer are disclosed. According to one aspect of the present invention, a method for processing transmission units received over a first network connection includes receiving a first transmission unit on the first network connection, storing the first transmission unit in a buffer, and determining when contents of the buffer meet a plurality of criteria. The method also includes sending a backpressure over the first network connection when it is determined that the contents of the buffer meet the plurality of criteria. In one embodiment, determining when the contents of the buffer meet a plurality of criteria includes determining when the contents of the buffer are of an amount that exceeds a threshold and determining when the contents of the buffer include at least one full packet.

摘要： A crossbar switch is provided that can allocate output port bandwidth both among multiple classes of service and among input ports. In one implementation, there are two scheduling stages that may be implemented together. One scheduling stage can select traffic for output based on class of service whereas the other scheduling stage may perform a further selection based on destination output port. This allows greater flexibility in managing congestion and allocating limited available bandwidth.

摘要： A method and a system for reducing the simultaneous switching output noise in integrated circuit chips. The method includes sending a previous bit pattern and a current bit pattern consecutively on the data bus, wherein the previous bit pattern transitions to the current bit pattern and the number of bits that transition is greater than half the number of bits in the data bus; flipping the current bit pattern to obtain an intermediate bit pattern; sending the intermediate bit pattern; receiving the intermediate bit pattern; and flipping the received intermediate bit pattern, to retrieve the current bit pattern.

摘要： A magnetoresistive write element has a plurality of coils disposed between a first and second pole. A first coil having inner and outer contacts is provided on top of a layer of insulation on top of the first pole. A write gap material above the first coil separates the poles at a yoke tip region to form a write gap therebetween. Second and third coils wound in the form of a single bifilar coil are provided on top of the write gap material, each having an inner and an outer contact portion. Electrical connection between the inner contact of the first coil and the inner contact of the second coil is provided through a via in the write gap material. An insulation layer above the second and third coils provides separation from a fourth coil provided thereabove. The fourth coil also has inner and outer contact portions. The outer contact of the fourth coil electrically connects with the outer contact of the second coil through one of the vias in the second insulation layer separating the second and third coil from the fourth coil. Similarly, the inner contact of the fourth coil connects electrically with the inner contact of the third coil. An insulation layer is deposited on top of the fourth coil and the second pole is formed on top thereof such that the first and second poles make electrical connection with one another at back gap portion.
