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.

Abstract: Systems and methods that allow for Dynamic Clock and Voltage Scaling (DCVS) aware interprocessor communications among processors such as those used in or with a portable computing device (“PCD”) are presented. During operation of the PCD at least one data packet is received at a first processing component. Additionally, the first processing component also receives workload information about a second processing component operating under dynamic clock and voltage scaling (DCVS). A determination is made, based at least in part on the received workload information, whether to send the at least one data packet from the first processing component to the second processing component or to a buffer, providing a cost effective ability to reduce power consumption and improved battery life in PCDs with multi-cores or multi-CPUs implementing DCVS algorithms or logic.

Abstract: Systems and methods for managing communications on a communication device are disclosed. A method may include receiving a communication packet at the communication device via a network connection and determining, at the communication device, whether the communication packet is an unsolicited control packet. Dormancy of the network connection is triggered after a first time period if the communication packet is not an unsolicited control packet, and dormancy of the network connection is triggered after a second time period if the communication packet is an unsolicited control packet wherein the second time period is less than the first time period.

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.

A determination is when there is a match between the at least one challenge response to the initial challenge and corresponding response data associated with the initial challenge.

Abstract: Systems and methods for dynamically adjusting an input parameter, such as power supply level, to a shared power domain in a portable computing device are disclosed. The power domain includes a plurality of processing resources that share the power source. The power supply level is reduced based on a critical core vote pool derived from votes from the plurality of processing resources. The critical core vote pool is narrowed from all the votes by disqualifying votes based on the operating status of the associated processing resources. For example, because inactive processing resources may be unaffected by a change in the voltage level to the shared domain, and because certain active processing resources are in a position to adjust to a power change dictated by another processing resource, such processing resources may be considered noncritical and their votes disqualified from consideration.

Abstract: The present disclosure relates to synchronization and parallel operation of two or more cores within a multi-core computing system so as to reduce an amount of time that all cores are operating during a processing period and thereby increase an amount of idle time per processing period. In this way deeper sleep and/or idle states for the cores and the system can be entered.

Abstract: An enhanced OnDemand Governor is disclosed that computes a steady-state frequency based on prior recommended CPU frequencies and applies a steady-state frequency when available. When not available, a turbo frequency or a computed lower frequency is applied. For increased loads, the steady-state frequency can be applied for one or more cycles until it becomes apparent that gradual frequency increases are not sufficient to meet a large CPU load, at which point the turbo frequency is applied and the history of CPU frequencies can be flushed. The enhanced OnDemand Governor can be turned on where periodic loads are detected while the traditional OnDemand Governor can be used in all other use cases.
