摘要： A method and structure for the handling and discarding of packets in a packet data network. The method includes a packet data network receiving one or more packets from one or more remote locations and initiating a transfer of a packet of the one or more packets to a remote destination. The remote destination is operable to act as a destination port of a switch. The transfer of the packet is initiated while the packet of the one or more packets is being received, and the packet validity is also checked while the transfer of the packet is initiated. If the packet is invalid, the transfer of the packet of the one or more packets to the remote destination is canceled. Determining packet validity includes inspection of a packet header. The structure has a receive link determining packet validity and passing this error signal to a packet processor. The packet processor has a packet transfer request generator, a packet checker, packet reader, packet memory and tag memory. The packet transfer request generator initiates a transfer request over a switch with a remote destination. While the request is processed, the packet checker verifies packet correctness and stores the packet data for transmission to the remote destination. If a packet is in error, a bad tag is set and the packet transfer is aborted.

摘要： In general, a system and method for providing data packet flow control is disclosed. Generally, a switch is provided that contains a series of ports, an arbiter and a hub. The arbiter determines an outgoing port, wherein the outgoing port is one port for the series of ports, for transmission of a data packet received by the switch, determines whether the outgoing port is available to receive the received data packet, and regulates transmission of the received data packet to a destination end node. The hub provides a point-to-point connection between any two of the series of ports and the arbiter.

摘要： A switch for use with an InfiniBand network. The switch includes a crossbar that redirects packet-based data based on a forwarding table. At least one port that receives data from a network and selectively transfers that data to the crossbar using a variable number of virtual lanes. A state machine controls the changing of the number of virtual lanes.

摘要： A computer graphics system includes an apparatus for fog blending colors to be displayed on a graphics display of the computer graphics system. The computer graphics system includes a rendering parameter calculation unit responsive to data of a primitive, that determines a cooked exponent value and a color value for at least one pixel of the primitive. In addition, the system includes a fog unit responsive to the cooked exponent value for each pixel of the primitive, that determines a fog blending factor for each pixel of the primitive, wherein the fog blending factor is one of an exponential fog blending factor and an exponential-squared fog blending factor. Further, the system includes a fog blending unit responsive to the color value and the fog blending factor for each pixel of the primitive and also to a fog color value, that blends the fog color value with the color value for each pixel of the primitive according to the fog blending factor for the respective pixel, and that provides a fogged color value for each pixel of the primitive. In addition, the computer graphics system may include a first interpolator, responsive to the color value and the cooked exponent value for at least one pixel of the primitive, that determines the color value and the cooked exponent value along an edge of the primitive so as to provide the cooked exponent value and the color value for each pixel of the edge of the primitive. Further, the computer graphics system may also include a second interpolator, responsive to the cooked exponent value and the color value for each pixel of the edge of the primitive, that determines the cooked exponent value and the color value along a span of the primitive so as to provide the cooked exponent value and the color value for each pixel of the span of the primitive. In this way, the system provides fast and accurate exponential and exponential-squared fog blending of the color values of the primitive without a lot of hardware.

摘要： A combination error detector to detect errors in an InfiniBand packet. The detector includes registers that stores fields of an InfiniBand packet as the packet is being received and comparison logic that, as the fields are stored in the registers, compares the fields with check values and when an error is detected sets a flag corresponding to the error. After the packet has been completely received and all checks have been complete, all of the error flags are prioritized in accordance with the InfiniBand Architecture Specification.

摘要： Regions of frame buffer memory are selectively read by a computer graphics system in a bandwidth efficient manor. Attribute data for each pixel is stored in the frame buffer memory array. This attribute data, when decoded, selects which regions of frame buffer memory are required for display of each pixel. Pixels are grouped as tiles. Before each tile is displayed, attribute data is read for that tile, then decoded, and the frame buffer memory is accessed only for those regions that are needed to display the current tile of pixels.
