Systems and methods to transfer master duties to a slave on a communication bus are disclosed. A master of a communication bus determines that one or more slaves are capable of serving as a sub-master, including providing a clock signal and owning control information bits. Once that determination is made, the master may determine that processing within the master is not required for a particular activity on the bus. The master then alerts one such capable slave to prepare to assume sub-master duties. Once the slave confirms that the slave is ready to assume the sub-master duties, the master may transmit a handover frame on the bus, and the slave begins acting as a sub-master. The master may then enter a low-power state, which may promote power savings, reduce heat generation, and provide other advantages.

Transfer of master duties to a slave on a communication bus

Certain aspects of the present disclosure relate to methods and apparatus for providing UDP receive offloading using the communications systems. For example, a method generally includes grouping, into a container, the datasets from the same source and destination arriving at a receiver based on datasets metadata, and ungrouping the datasets from the container once network layer processing on the container is completed and datasets are ready to traverse to a next destination.

User datagram protocol (UDP) receive offloading

Data bus activation in an electronic device is provided. In one aspect, a host circuit determines a cumulative potential representing a cumulative fractional bus activation vote on a data line(s) in the data bus. The host circuit activates the data bus when the cumulative potential is greater than a configurable bus activation threshold. In another aspect, a device circuit(s) determines a selected signal strength threshold that is less than determined signal strength of an incoming signal. Accordingly, the device circuit(s) asserts a fractional potential corresponding to the selected signal strength threshold on the data line(s) as a fractional bus activation vote in the cumulative fractional bus activation vote. By activating the data bus based on the cumulative fractional bus activation vote, the host circuit can support timely data bus activation while preventing the data bus from being falsely activated, thus improving robustness of data bus activation in the electronic device.

M-PHY communications are provided over a mass storage-based interface. Related connectors, systems, and methods are also disclosed. In particular, embodiments of the present disclosure take the M-PHY standard compliant signals and direct them through a memory card compliant connector so as to allow two M-PHY standard compliant devices having memory card based connectors to communicate.

Operating M-PHY based communications over mass storage-based interfaces, and related connectors, systems and methods

A method, an apparatus, and a computer program product for communication are provided. The apparatus aggregates data sets as a function of an estimated characteristic of a next data set to arrive, and adaptively adjust the estimated characteristic based on a statistical measure of the estimated characteristic derived from a plurality of previously arrived data sets. The estimated characteristic may be an estimated next arrival time of the next data set, or an estimated size of the next data set.

Dynamic adaptive aggregation schemes for enhancing performance of communication systems

Embodiments disclosed herein include operating the M-PHY communications over peripheral component interconnect (PCI)-based interfaces. Related cables, connectors, systems, and methods are also disclosed. In particular, embodiments disclosed herein take the M-PHY standard compliant signals and direct them through a PCI compliant connector (and optionally cable) so as to allow two M-PHY standard compliant devices having PCI connectors to communicate.

A mobile device having an identifier supports a mobile server hosting an HTML web site. The mobile device is power cycled according to an ON-OFF timing defined by timing parameters. An association between the timing parameters and the identifier of the mobile device is provided. A web client sends a request to access the mobile device, using a public mobile device identifier. Optionally, the public mobile device identifier is mapped to identify ON-OFF timing parameters of the mobile device, and web client access to the mobile device is controlled based on the ON-OFF timing parameters.

Remote access and administration of device content, with device power optimization, using HTTP protocol

A communications system includes a mobile computing device having a dynamic address and mobile web server software. A network web server has a portal web page at which a web client can reliably and consistently establish an internet connection. In response to receiving a request from the web client to access the mobile computing device, the network web server re-routes the web client from a static address of the network web server to the assigned address of the mobile computing device. The mobile computing device repeatedly registers the current version of its address with the network web server. The mobile computing device, network web server and web client are commercially available, off-the-shelf components that require only targeted configuration changes to perform the disclosed re-routing operations.

System and method for accessing a device having an assigned network address

A mobile device supports a mobile server hosting an HTML web site. The mobile device has an identifier and receives dynamically updated IP addresses from a network connected through a firewall to the Internet. The mobile device reports received updates of the IP address to an HTTP server in the network that interfaces with the Internet. The HTTP server updates a redirect address record associating the identifier of the mobile device with the reported IP address. The HTTP server receives, from a web browser in the Internet, an HTTP request having the identifier of the mobile device. The HTTP server, using the redirect address record, redirects the web browser to the mobile device. The web browser sends an HTTP request directly to the mobile device.

Remote access and administration of device content and configuration using HTTP protocol

A communications system includes a mobile computing device having a dynamic address and mobile web server software. A network web proxy-server has a portal web page at which a web client can reliably and consistently establish an internet connection. In response to receiving a request from the web client to access the mobile computing device, the network web proxy-server forwards the request to the mobile computing device by opening an indirect or virtual communications link between the web client, the network web proxy-server and the assigned address of the mobile computing device. The mobile computing device repeatedly registers the current version of its address with the proxy-server. The mobile computing device, network web proxy-server and web client are commercially available, off-the-shelf components that require only targeted configuration changes to perform the disclosed intermediary forwarding operations.

System and method using a web proxy-server to access a device having an assigned network address

A communications system includes a mobile computing device having a dynamic address and mobile web server software. A client-local proxy-server has an IP address to which a web client can reliably and consistently establish an internet connection. In response to receiving a request from the web client to access the mobile computing device, the client-local proxy-server acts as an intermediary opening up a communications path between the web client and the assigned address of the mobile computing device. The mobile computing device repeatedly registers the current version of its address with the client-local proxy-server. The mobile computing device and proxy-server software require only targeted configuration changes to perform the disclosed intermediary routing operations.
