TL;DR: In this article, the potential of architectural techniques to reduce leakage through power-gating of execution units was explored, for the range of relevant break-even points determined by the analytical equations, using a state-of-the-art out-oforder superscalar processor model.
Abstract: Leakage power is a major concern in current and future microprocessor designs. In this paper, we explore the potential of architectural techniques to reduce leakage through power-gating of execution units. This paper first develops parameterized analytical equations that estimate the break-even point for application of power-gating techniques. The potential for power gating execution units is then evaluated, for the range of relevant break-even points determined by the analytical equations, using a state-of-the-art out-of-order superscalar processor model. The power gating potential of the floating-point and fixed-point units of this processor is then evaluated using three different techniques to detect opportunities for entering sleep mode; ideal, time-based, and branch-misprediction-guided. Our results show that using the time-based approach, floating-point units can be put to sleep for up to 28% of the execution cycles at a performance loss of 2%. For the more difficult to power-gate fixed-point units, the branch misprediction guided technique allows the fixed-point units to be put to sleep for up to 40% more of the execution cycles compared to the simpler time-based technique, with similar performance impact. Overall, our experiments demonstrate that architectural techniques can be used effectively in power-gating execution units.

7 Jul 2004TL;DR: In this article, a method and system for efficiently managing power consumption in a mobile device controls power consumption with an adjustable sleep period or listening interval that may be user-specified and automatically tuned based on recent detected usage.
Abstract: A method and system for efficiently managing power consumption in a mobile device controls power consumption with an adjustable sleep period or listening interval that may be user-specified and automatically tuned based on recent detected usage. With an adjustable sleep period, a receiver conserves power by leaving a sleep mode only at predefined and adjustable periods, which may be selected by the user to balance connectivity and power saving and which may be automatically incremented when the device activity is low.

TL;DR: In this article, the authors proposed a communications system comprising a first communications device for receiving data and a wake up signal, which consists of an active mode of operation and a sleep mode for reducing power consumption.
Abstract: The present invention teaches a communications system comprising a first communications device for receiving data and a wake up signal. The first communications device comprises an active mode of operation and a sleep mode of operation for reducing power consumption. Further, the system comprises means for switching the first communications device to and from sleep mode in response to receiving the wake up signal. Further, the system comprises a second communications device for transmitting data to the first device during its active mode, while transmitting the wake up signal to the first device during its sleep mode.

TL;DR: This work presents a new predictive system shutdown method to exploit sleep mode operations for power saving, using an exponential-average approach to predict the upcoming idle period and introduces two mechanisms, prediction-miss correction and pre-wakeup, to improve the hit ratio and to reduce the delay overhead.
Abstract: We present a system-level power management technique for power saving of event-driven applications. We present a new predictive system shutdown method to exploit sleep mode operations for power saving. We use an exponential-average approach to predict the upcoming idle period. We introduce two mechanisms, prediction-miss correction and pre-wakeup, to improve the hit ratio and to reduce the delay overhead. Experiments on four different event-driven applications show that our proposed method achieves high hit ratios in a wide range of delay overheads, which results in a high degree of power saving with low delay penalties.

TL;DR: A new multithreshold-voltage CMOS circuit (MTCMOS) concept aimed at achieving high-speed, ultralow-power large-scale integrators (LSI's) for battery-driven portable equipment and the "balloon" circuit scheme based on this concept preserves data during the power-down period.
Abstract: This paper proposes a new multithreshold-voltage CMOS circuit (MTCMOS) concept aimed at achieving high-speed, ultralow-power large-scale integrators (LSI's) for battery-driven portable equipment. The "balloon" circuit scheme based on this concept preserves data during the power-down period in which the power supply to the circuit is cut off in order to reduce the standby power. Low-power, high-speed performance is achieved by the small preserving circuit which can be separated from the critical path of the logic circuit. This preserving circuit is not only three times faster than a conventional MTCMOS one, but it consumes half the power and takes up half the area. Using this scheme for an LSI chip, 20-MHz operation at 1.0 V and only a few nA standby current was achieved with 0.5-/spl mu/m CMOS technology. Moreover, this scheme is effective for high speed and low-power operation in quarter-micrometer and finer devices.
