摘要： An apparatus and method for controlling idle mode in an electronic device. In idle mode, power and clock signals are reduced or stopped to conserve power. The apparatus includes a target module coupled to a power and clock control module (PCCM). The PCCM sends an idleack signal to the target module when at least one initiator module within the device is in a power saving mode. When the target module satisfies conditions for idle mode, the target module sends an idleack signal to the PCCM and enters idle mode. In this state, the target module may process information but may not interact with other modules. When the target module detects a wakeup event, a wakeup signal is sent to the PCCM. When the PCCM returns the normal power and clock signal to the target module, the target module may resume normal operation.

摘要： An apparatus and method for conserving power in a memory information transfer system. The system may include a direct memory access (DMA) controller coupled to a memory storage device and a peripheral device. The DMA controller transfers information from the memory storage device to a buffer in the peripheral device. The DMA controller may also transfer information from the buffer in the peripheral device to the memory storage device. When the peripheral device buffer does not have to be filled or emptied by the DMA controller, the DMA controller enters a standby mode. When the peripheral device buffer is full or empty, the DMA controller exits standby mode, empties or fills the peripheral device buffer, and reenters standby mode.

摘要： An apparatus and method for controlling standby mode in an electronic device. In standby mode, power and clock signals are reduced or stopped to conserve power. The apparatus includes an initiator module coupled to a power and clock control module (PCCM). When the initiator module meets conditions for standby mode, the initiator module sends a standby signal to the PCCM and does not interact with other initiator, target, or interconnect modules. When the PCCM communicates a wait signal, the initiator module enters standby mode. When the initiator module detects a wakeup event, the standby signal is deactivated. In this state, the initiator module may process information but may not interact with other modules. When the PCCM deactivates the wait signal and returns power and clock signal to steady state levels, initiator module may resume normal operation.

摘要： An apparatus and method for dynamically modifying one or more operating conditions of a memory controller in an electronic device. Operating conditions may comprise clock frequency and power, which may be modified or removed. Dynamic modification of operating conditions may be done for purposes of optimizing a parameter, such as power consumption. A mode, referred to as idle mode, may be used as a transitional or operational mode for the memory controller. The performance of the memory controller may dynamically vary in response to changes in its operating conditions. As such, the memory controller may comprise multiple modes, or submodes, of operation. The performance of the memory controller may depend on the type of memory it controls, for instance Double Data Rate (DDR) Dynamic Random Access Memory (DRAM).

摘要： An apparatus for clock/voltage scaling includes a device power manager arranged to supply a scalable frequency clock to an interface; a delay-locked loop, supplied by a constant fixed frequency clock and a constant voltage, arranged to generate a unique code depending on process, voltage, and/or temperature; and controlled delay line elements coupled to the delay-locked loop, arranged to generate an appropriate delayed data strobe based on the unique code. A method for a digital phase lock loop high speed bypass mode includes providing a first digital phase lock loop in a first high speed clock domain; providing a second digital phase lock loop in a second clock domain; controlling an output of a first glitchless multiplexer according to preselected settings using a device power manager synchronized locally; and controlling an output of a second glitchless multiplexer using a control logic element of the second digital phase lock loop.
