  • Patent number: 9671857
    Abstract: Systems and methods for dynamically adjusting an input parameter to a power domain in a portable computing device are disclosed. The power domain includes two or more processing resources that share a power source. Dynamic use of the two or more processing resources creates an opportunity to adjust the input parameter when a status change associated with a processing resource in the power domain occurs. A controller in the power domain includes logic that responds to a status indicator associated with a respective processing resource in the power domain by generating a control signal that directs a device to adjust one or both of input voltage and clock frequency.

  • Patent number: 9652022
    Abstract: Systems and methods that allow for dynamic quality of service (QoS) levels for an application processor in a multi-core on-chip system (SoC) in a portable computing device (PCD) are presented. During operation of the PCD an operational load of a co-processor of the SoC is determined, where the co-processor is in communication with an application processor of the SoC. Based on the determined load, the co-processor determines a QoS level required from the application processor. The QoS level is communicated to the application processor. The application processor determines whether it can implement power optimization measures, such as entering into a low power mode (LPM), based at least in part on the dynamically communicated QoS level from the co-processor. The present disclosure provides a cost effective ability to reduce power consumption in PCDs implementing one or more cores or CPUs that are dependent upon the application processor.

  • Publication number: 20170075783
    Abstract: During a storage redundancy giveback from a first node to a second node following a storage redundancy takeover from the second node by the first node, the second node is initialized in part by receiving a node identification indicator from the second node. The node identification indicator is included in a node advertisement message sent by the second node during a giveback wait phase of the storage redundancy giveback. The node identification indicator includes an intra-cluster node connectivity identifier that is used by the first node to determine whether the second node is an intra-cluster takeover partner. In response to determining that the second node is an intra-cluster takeover partner, the first node completes the giveback of storage resources to the second node.

  • Publication number: 20170038999
    Abstract: Systems and methods for improved implementation of low power modes in a multi-core system-on-a-chip (SoC) are presented. A cache memory of the multi-core SoC not being accessed by other components of the SoC is identified and a number of dirty cache lines present in the cache memory is determined. For a low power mode of the core, an entry latency based on the number of dirty cache lines is determined, and an exit latency is determined. An entry power cost for the low power mode is also determined based on the number of dirty cache lines A determination is made whether the low power mode for the cache memory results in a power savings over an active mode for the cache memory based at least on the entry power cost and the entry latency of the cache memory entering the first power mode.

  • Publication number: 20170041687
    Abstract: Embodiments of present disclosure relates to a method and an interactive infomercial system for enabling interactive infomercials. In one embodiment, data associated with user of viewing interactive infomercial content may be received on a mobile viewing device. The system may select one interactive infomercial content based on the received data. Upon selection, at least one infomercial unit comprising the at least one interactive infomercial content such as animation content, a unique infomercial identification information (U3I) associated with the selected interactive infomercial content is generated and transmitted to the mobile viewing device of the user. The mobile viewing device receives and downloads the animation content and enables connecting back with the system for further interactions. Thus, the system and method enables real-time interactive infomercials to the users without consuming memory of the mobile viewing device as well as without modifying the U3I associated with the infomercial content.

  • Publication number: 20170038813
    Abstract: Systems and methods for improved implementation of low power modes in a multi-core system-on-a-chip (SoC) are presented. A core of the multi-core SoC entering an idle state is identified. For a low power mode of the core, an entry power cost of the core and an exit power cost of the core is calculated. A working set size for a cache associated with the core is also calculated. A latency for the cache to exit the low power mode of the core is calculated using the working set size. Finally, a determination is made whether the low power mode for the core results in a power savings over an active mode for the core based in part on the entry and exit power costs of the core, and the latency of the cache exiting the low power mode.

  • Patent number: 9444148
    Abstract: A printed quasi-tapered tape helical element and printed helical array antenna. The helical element comprises a thin helix conductor having a uniform section associated with a tapered section. The helix conductor can be printed on a thin dielectric sheet and bonded to a hollow composite dielectric support. A solid copper conductor is configured to provide electrical connection between a feeding point of the helix conductor and a microstrip line of a microstrip feed network. The uniform and tapered helix turns are respectively wrapped around the uniform and tapered sections, which enables impedance matching, axial mode excitation, gain and radiation patterns, and damping out of standing waves generated in current distribution over the helix conductor. Conductive composite cups surrounding each helical element reduces mutual coupling in array environment. Thus, the helical element and the array antenna achieve low on-axis and off-axis axial ratio performance over the wideband for global coverage.

  • Publication number: 20160203083
    Abstract: A dynamic cache extension in a multi-cluster heterogeneous processor architecture is described. One embodiment is a system comprising a first processor cluster having a first level two (L2) cache and a second processor cluster having a second L2 cache. The system further comprises a controller in communication with the first and second L2 caches. The controller receives a processor workload input and a cache workload input from the first processor cluster. Based on processor workload input and the cache workload input, the cache controller determines whether a current task associated with the first processor cluster is limited by a size threshold of the first L2 cache or a performance threshold of the first processor cluster. If the current task is limited by the size threshold of the first L2 cache, the controller uses at least a portion of the second L2 cache as an extension of the first L2 cache.
