摘要:
A method and apparatus for signaling virtual channel support in communication networks. A node receives a data packet from another node to examine whether the other node commonly supports one or more virtual channels of a given type on a point-to-point communication link between the nodes, and the node signaling common support for one or more virtual channels of a given type, based on the content in the received data packet that indicates whether the other node transmitting the data packet has adequate queue resources to support one or more virtual channels of a given type, and based on whether the node has adequate queue resources to support the one or more virtual channels of a given type.

A switching fabric handles transactions using a protocol that directs packets based on path routing information. Components participate in transactions using a protocol that issues packets based on physical location of a destination device over the switching fabric, by establishing a virtual link partner relationship between the components.

A bridge has a first interface that receives a request through a first bus from a requestor that request to read data, and a second interface that forwards the request through a second bus to a device that connects to a memory. The device obtains the requested data from the memory and forwards to the bridge, which then sends the data to the requestor in an appropriate manner.

Disclosed are a system and method of transmitting data in a processing platform. A switch may comprise an upstream port coupled to a root device to communicate with a processing system. The switch may also comprise a plurality of downstream ports where each downstream port is adapted to be coupled to a device. Data may be transmitted between downstream ports based upon routing information for transmitting data from the upstream port to each of the downstream ports.

A method and device are provided for managing a group of electrical devices, e.g., coder/decoders (codecs) in a computer system. Members of a group of electrical devices may be located on the motherboard of the computer system, or off the motherboard, such as on a riser card. An address ID module assigns a primary address to designate one of the devices as a primary device. The primary device performs certain functions that are only performed by a single device. Other devices are designated as secondary devices. A signal indicates whether a member of the group of electrical devices is located on the motherboard. If no device is located on the motherboard, the address ID module designates a primary device and secondary devices from among the devices located on the riser card. A routing module routes output signals from the devices to input pins of a controller. If a device is located on the motherboard, it is designated as the primary device by the address ID module, and the other devices are designated secondary devices. A routing module shifts the routing of the output signals from the secondary devices to different pins on the controller.

An apparatus for processing visual information includes a controller to control display of information in an application window based on first visual information stored in a buffer and second visual information received from one or more sources. The controller outputs the first visual information for display in a first area of the application window and outputs the second visual information for simultaneous display in a second area of the application window. The first visual information is visual information that does not change between a first time and a second time, and the second visual information is visual information that changes between the first time and the second time. The controller may be different from a central processing unit of a host device.

摘要:
A distributed power management system for a bus architecture or similar communications network. The system supports multiple low power states and defines entry and exit procedures for maximizing energy savings and communication speed.

A method for accessing a configuration space of a device is described. The method includes setting a first field of a packet to a value to specify a destination device, and setting a second field of the packet to a defined value to indicate that the packet is a configuration access packet. The method further includes setting a third field of the configuration access packet to a value to select one of a plurality of configuration apertures of a configuration space of the destination device, and setting a fourth field of the configuration access packet to a value to address a specific memory location within the selected aperture.
