  • Publication number: 20230276303
    Abstract: A host device establishes a wireless communication link with a client device, and implements a wired communication standard on the link to transfer a first data stream. To increase data throughput while complying with the standard, the host device replaces synchronizing information in a packet to be sent during a first synchronizing frame with configuration information indicating that packet exchange data of a second data stream is to be sent or received during a second synchronizing frame. The host device sends or receives the packet exchange data of the second data stream to or from the client device during the second synchronizing frame via the wireless communication link. The host device may send or receive the packet exchange data of the second data stream during delays or idle periods between sending and/or receiving packets of the first data stream via the wireless communication link according to the wired communication standard.

  • Patent number: 7114058
    Abstract: Methods and apparatuses for dispatching instructions executed by at least one functional unit of a data processor, each one of the instructions having a corresponding priority number, in a data processing system having at least one host processor with host processor cache and host memory are described herein. In one aspect of the invention, an exemplary method includes receiving a next instruction from an instruction stream, examining a current instruction group to determine if the current instruction group is completed, adding the next instruction to the current instruction group if the current instruction group is not completed, and dispatching the current instruction group if the current instruction group is completed.
