  • Patent number: 11054883
    Abstract: A power management algorithm framework proposes: 1) a Quality-of-Service (QoS) metric for throughput-based workloads; 2) heuristics to differentiate between throughput and latency sensitive workloads; and 3) an algorithm that combines the heuristic and QoS metric to determine target frequency for minimizing idle time and improving power efficiency without any performance degradation. A management algorithm framework enables optimizing power efficiency in server-class throughput-based workloads while still providing desired performance for latency sensitive workloads. The power savings are achieved by identifying workloads in which one or more cores can be run at a lower frequency (and consequently lower power) without a significant negative performance impact.

  • Patent number: 10613619
    Abstract: Techniques and apparatuses are described that provide an ultra-low power mode for a low-cost force-sensing device. These techniques extend battery life of the device by minimizing power consumption for potential wake-up events. To do this, a high-pass filter (e.g., differentiator) is used to evaluate sensor signals in a time domain to provide an estimate of a rate of change of the signal. When the rate of change of the signal deviates from a baseline value by a threshold amount, then a microcontroller is woken to evaluate a large number of historical samples, such as 200 or more milliseconds worth of historical data. If a human gesture is not recognized, then the microcontroller returns to an idle state, but if a human gesture is recognized, then a high-power application processor is woken to execute an application configured to perform an operation mapped to the human gesture.

    Abstract: A data processing system includes a plurality of transaction masters, each with an associated local cache memory and coupled to coherent interconnect circuitry. Monitoring circuitry within the coherent interconnect circuitry maintains a state variable (flag) in respect of each of the transaction masters to monitor whether an exclusive store access state is pending for that transaction master. When a transaction master is to execute a store-exclusive instruction, then a current value of the subject state variable for that transaction master is compared with a previous value of that variable stored when the exclusive store access was setup. If there is a match, then store-exclusive instruction is allowed to proceed and the state variables of all other transaction masters for which there is a pending exclusive store access state are changed. If there is not a match, then the execution of the store-exclusive instruction is marked as failing.

Resource parameters are specified for each task to define the amount of resources allocated for consumption by each array of execution threads that is launched to execute the task. The resource parameters also specify the behavior of the array for acquiring and releasing resources. Finally, during execution of each thread in the array, an exit instruction may be configured to override the release of the resources that were allocated to the array. The resources may then be retained for use by a child task that is generated during execution of a thread.

  • Publication number: 20150127925
    Abstract: A data stream processing unit (DPU) and method for use are provided. A DPU includes a number of processing elements arranged in a sequence, and each datum in the data stream visits each processing element in sequence. Each processing element has a memory circuit, data and metadata input and output channels, and a computing circuit. The metadata input represents a partial computational state that is associated with each datum as it passes through the DPU. The computing circuit for each processing element operates on the data and metadata inputs as a function of its position in the sequence, producing an altered partial computational state that accompanies the datum. Each computing circuit may be modeled, for example, as a finite state machine, and the collection of processing elements cooperate to perform the computation. The computing circuits may be collectively programmed to perform any desired computation.
