Abstract: There is provided a method of controlling performance boosting of a semiconductor device. According to the method, input of a user is monitored. A performance of the semiconductor device is boosted by consecutively executing a plurality of boosting policies associated with a plurality of macros based on an input event associated with the input of the user and available energy during a boosting interval. Boosting level in each of the boosting policies may be adaptively determined based on the boosting level and the amount of usage of the semiconductor device used in the previous boosting policy and the boosting policies are consecutively executed. Accordingly, improved and/or optimal performance boosting can be provided to the semiconductor device and at the same time, a waste of power can be mitigated and/or prevented.

Abstract: A real-time workload scheduling heuristic assigns tasks to the cores such that the total load current consumption of the cores is always less than the total current capability of the under-provisioned on-chip voltage regulators. In addition, the energy-efficient scheduling of the tasks on to the cores ensures that the reconfiguration of the power delivery network is minimized. The heuristic includes DVFS management based on the unique constraints of the under provisioned voltage regulators.

Abstract: A method of tuning performance of a data storage system includes calculating an estimate of parallel fraction and speedup characteristic for a data storage application executed by the data storage system. The estimate is calculated using linear regression of values (1/N, 1/XN) that are generated from trial runs of the data storage application processing a workload using respective different numbers N of CPU cores to obtain corresponding performance values XN. The method further includes configuring the data storage system to execute the data storage application using a number of CPU cores based on the estimate of parallel fraction and speedup characteristic.

Abstract: A memory device includes a power supply device, a power-on-reset device, a memory array, and a memory controller. The power supply device converts the external supply voltage into an internal supply voltage. When the external supply voltage exceeds a first threshold, the power-on-reset device generates a reset signal. The power-on-reset device further raises the first threshold to a second threshold according to a deep-sleep signal. The memory array is supplied with the internal supply voltage. The memory controller is supplied with the internal supply voltage, accesses the memory array, and is reset according to the reset signal. When the memory controller operates in a deep-sleep mode, the memory controller generates the deep-sleep mode.

Abstract: Applications can be selectively offloaded to ensure that thin clients will have sufficient disk space to install an update. To enable this offloading, a service can be employed to track how long each application is used on the thin client during a particular time period. Based on this usage of each application, the service can assign a rank to each application. The service can also monitor the amount of free space on the disk to determine whether it has fallen below a threshold. If so, the service can employ the ranks to identify applications to be offloaded them by copying an install location folder for each application to a remote repository and then deleting each copied install location folder. When the thin client includes a write filter, the service can commit the deletes of the install location folders so that the applications will remain offloaded after reboot.
