In one example, a data center may be built in modular components that may be pre-manufactured and separately deployable. Each modular component may provide functionality such as server capacity, cooling capacity, fire protection, resistance to electrical failure. Some components may be added to the data center by connecting them to the center's utility spine, and others may be added by connecting them to other components. The spine itself may be a modular component, so that spine capacity can be expanded or contracted by adding or removing spine modules. The various components may implement functions that are part of standards for various levels of reliability for data centers. Thus, the reliability level that a data center meets may be increased or decreased to fit the circumstances by adding or removing components.

Context-based adaptations of video decoder

A receive device receives video data in the form of an encoded video bit stream. A video decoder of the receive device identifies a portion of the video data corresponding to a first scene and determines a complexity for this first scene and also determines a quality of service for the receive device. If the complexity of the first portion of video data is greater than a complexity threshold value or the quality of service is less than a quality of service threshold value, then the video decoder uses a hardware accelerator to decode the portion of video data. If, however, the complexity of the portion of video data is less than the complexity threshold value and the quality of service is greater than the quality of service threshold value, then the video decoder may use software decoding to decode the portion of video data.

Techniques for employing a decentralized sleep management service are described herein. In some instances, each computing device of a group of computing devices periodically shares information about itself with each other computing device of the group. With this information, each computing device within the group that is awake and capable of managing other devices selects a subset of devices to probe. The devices then probe this subset to determine whether the probed devices are asleep. In response to identifying a sleeping device, the probing device takes over management of the sleeping device. Managing the sleeping device involves informing other devices of the group that the sleeping device is being managed, in addition to monitoring requests for services on the sleeping device. In response to receiving a valid request for a service hosted by the sleeping device, the managing device awakens the sleeping device and ceases managing the now-woken device.

An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells.

A runtime management system is described herein that allows a hosting layer to dynamically control an underlying runtime to selectively turn on and off various subsystems of the runtime to save power and extend battery life of devices on which the system operates. The hosting layer has information about usage of the runtime that is not available within the runtime, and can do a more effective job of disabling parts of the runtime that will not be needed without negatively affecting application performance or device responsiveness. The runtime management system includes a protocol of communication between arbitrary hosts and underlying platforms to expose a set of options to allow the host to selectively turn parts of a runtime on and off depending on varying environmental pressures. Thus, the runtime management system provides more effective use of potentially scarce power resources available on mobile platforms.

The ER may indicate relative advantage among domains in terms of performance return for a given power budget, i.e., a higher effectiveness may be expected in power utilization if the ER is higher for a domain. The ER of a domain may be defined as (scalability factor/cost factor*alpha). The scalability factor may be defined as a performance increase (in %) brought about by an increase in the clock frequency (in %) provided to the domain. The cost factor may be defined as a power budget value required in bringing about an increase in the clock frequency provided to the domain and alpha is an adjustment factor.

Semiconductor Integrated Circuit and Control Method for Clock Signal Synchronization

Номер: US20120187993A1
Автор: Makoto Saen, Masafumi Onouchi, Shigenobu Komatsu, Yusuke Kanno
Принадлежит: Individual

There is a need to ensure operation performance of a circuit region under DVFS control at low costs and highly precisely while a power-supply voltage change is made to the region. A first circuit (FVA) uses a first power-supply voltage (VDDA) for operation. A second circuit (NFVA) uses a second power-supply voltage (VDDB) for operation. A clock delay may be adjusted between paths for transmitting a clock to these circuits. When VDDA equals VDDB, a clock is distributed to FVA through a path that does not contain a delay device for phase adjustment. When the power-supply voltage for the FVA region is reduced, a clock is distributed to the FVA region based on a phase equivalent to one or two cycles of the clock displaced. Synchronization control is provided to synchronize clocks (CKAF and CKBF) and ensures operation so that a phase of two clocks to be compared fits in a range of design values while the power-supply voltage for the first circuit is changed.
