    Abstract: Systems and methods are provided for managing power in a processing system. In one embodiment, a target system having a plurality of electronic devices is operated within a net power limit. A local controller detects power consumption for each device, and communicates the power consumption to a power management module. The power management module dynamically apportions the net power limit among the devices, and communicates the apportioned power limit for each device back to the associated local controller. Each local controller enforces the apportioned power limit to an associated device on behalf of the power management module.

    Abstract: A mechanism is provided for scheduling application tasks. A scheduler receives a task that identifies a desired frequency and a desired maximum number of competing hardware threads. The scheduler determines whether a user preference designates either maximization of performance or minimization of energy consumption. Responsive to the user preference designating the performance, the scheduler determines whether there is an idle processor core in a plurality of processor cores available. Responsive to no idle processor being available, the scheduler identifies a subset of processor cores having a smallest load coefficient. From the subset of processor cores, the scheduler determines whether there is at least one processor core that matches desired parameters of the task. Responsive to at least one processor core matching the desired parameters of the task, the scheduler assigns the task to one of the at least one processor core that matches the desired parameters.

    Abstract: A method and systems for optimizing Asymmetric Digital Subscriber Line (ADSL) connections in DSL Access Multiplexor (DSLAM) that marries benefits of G.dmt and G.lite standards, using a flexible method implemented on a programmable Digital Signal Processor (DSP) and a Network Processor (NP) is disclosed. It provides a means to support full G.dmt rates for any of the attached users as long as less than half the users are actively moving data through the DSLAM, but by only using half the digital signal processing hardware and half the power consumption for the line drivers. The invention allows doubling the number of,ADSL ports available over a conventional scheme given about 20% more power is under 50% with only half the respective connections, all those G.dmt rates possible on their exceeds 50%, gradually active G.lite rates based on either based on a tiered tariff structure, until ultimately, when the utilization reaches 100%, all subscribers will be forced back to a maximum rate afforded by G.lite. Only as utilization drops back off, will active subscribers be brought back up to G.dmt's maximum transmission rates. Once the utilization drops below 50% again, then all active subscribers will be able to utilize G.dmt's maximum transmission rates. budget. When the utilization subscribers active on their users experience the maximum wire. However, when utilization subscribers start to experience a fixed policy or one that is based on a tiered tariff structure, until ultimately, when the utilization reaches 100%, all subscribers will be forced back to a maximum rate afforded by G.lite. Only as utilization drops back off, will active subscribers be brought back up to G.dmt's maximum transmission rates. Once the utilization drops below 50% again, then all active subscribers will be able to utilize G.dmt's maximum transmission rates.
