  • Publication number: 20120281711
    Abstract: Network Interface Controller (NIC) logic may receive a packet comprising a routing parameter indicating a service or cost to be utilized in processing the packet. The NIC logic may determine a selected virtual machine (VM) running on a network device to process the packet according to the routing parameter. The NIC logic may communicate the packet across a network after the packet has been processed by the selected virtual VM. Or, the NIC logic may initialize a VM in the network device to process the packet according to the routing parameter. The NIC logic may receive multiple packets and determine a second selected VM or initialize a second VM to process the multiple packets according to the respective routing parameters of the multiple packets. The routing parameters may indicate device capabilities, service class, quality measurements, latency, power usage or any combination thereof.

  • Publication number: 20120250877
    Abstract: A central audio hub, comprising an audio switch, a bus matrix, and an audio buffer, is triggered to read audio samples of an audio stream from the audio buffer. The central audio hub routes the audio samples via the bus matrix to one or more surrounding audio modules such as an audio codec and an audio interface communicatively coupled to the central audio hub. The audio stream may be directly from an external application processor or from an external DDR. With the audio stream from the DDR, a DMA controller may fetch the audio samples from the DDR in response to a request received from the audio buffer, and store the fetched audio samples into the audio buffer for routing. The audio switch may be triggered at a determined sampling rate to read the audio samples from the audio buffer utilizing a determined sample format, and to route the audio samples to the surrounding audio modules.
