摘要： A power management technique is provided that operates with regard to a dynamic sleep threshold voltage. If a device's battery voltage is greater than the dynamic sleep threshold voltage, a voltage rail for the device is collapsed during a sleep mode for the device. Conversely, if the battery voltage is less than the dynamic sleep threshold voltage, the voltage rail is sourced during the sleep mode for the device.

摘要： Various embodiments of methods and systems for hardware (HW) based dynamic memory management in a portable computing device (PCD) are disclosed. One exemplary method includes generating a lookup table (LUT) to track each memory page located across multiple portions of a volatile memory. The records in the LUT are updated to keep track of data locations. When the PCD enters a sleep state to conserve energy, the LUT may be queried to determine which specific memory pages in a first portion of volatile memory (e.g., an upper bank) contain data content and which pages in a second portion of volatile memory (e.g., a lower bank) are available for receipt of content. Based on the query, the location of the data in the memory pages of the upper bank is known and can be quickly migrated to memory pages in the lower bank which are identified for receipt of the data.

摘要： Methods and apparatuses for memory power reduction are provided. The apparatus determines whether to store data into a DRAM or an NVRAM during an idle state of a processor based on power consumption by the DRAM in association with refreshing the data in the DRAM and use of the data stored in the DRAM by the processor, based on power consumption by the NVRAM in association with use of the data stored in the NVRAM by the processor, and based on a duty cycle associated with current drawn in a first power state and a second power state in association with the data. The NVRAM is a type of non-volatile random-access memory other than flash memory. The processor stores the data into one of the DRAM or the NVRAM based on the determination whether to store the data in the DRAM or the NVRAM.

摘要： A method includes initiating a transition from an operating mode to a sleep mode at an electronic device that includes a volatile memory and a non- volatile memory. In response to the initiating, data is copied from the volatile memory to the non-volatile memory and a portion of the volatile memory is disabled. Another method includes determining that a low performance mode condition is satisfied at an electronic device that includes a volatile memory that stores a first copy of read-only data and a non-volatile memory that stores a second copy of the read-only data. A memory mapping of the read-only data is updated from the volatile memory to the non- volatile memory. A portion of the volatile memory that stores the first copy is disabled and access of the read-only data is directed to the non-volatile memory instead of the volatile memory.

摘要： Techniques for performing searches by a user equipment (UE) are described. The UE may camp on a serving cell for a first radio access technology (RAT) (e.g., GSM) and may periodically perform searches for a second RAT (e.g., WCDMA). In an aspect, the UE may vary the rate of searches for the second RAT based on received signal levels for the first and second RATs. The UE may determine a difference between the received signal levels for the two RATs, compare the difference against at least one threshold, and select a search rate associated with a range within which the difference falls as the rate of searches for the second RAT. In another aspect, the UE may control certain aspects of searches (e.g., determine whether or not to perform searches or the rate of searches) for the second RAT by considering the frequency bands for the two RATs.

摘要： Techniques for operating a diversity receiver are described. A user equipment (UE) may include (i) a first receive chain having an equalizer and a first rake receiver and (ii) a second receive chain having a second rake receiver. The UE may support (i) a first mode in which only the equalizer is used to process a received transmission and (ii) a second mode in which both rake receivers are used to process the received transmission. The UE may determine a first performance metric for the first mode (e.g., based on the performance of the equalizer) and a second performance metric for the second mode (e.g., based on the performance of both rake receivers or only the first rake receiver). The UE may select the first or second mode based on the performance metrics and may power down the second receive chain if the first mode is selected.

摘要： Various embodiments in the disclosure provide methods implemented by a processor executing on a mobile communication device to dynamically determining whether the power saved by powering down the RF chain between the end of the last reception activities and the beginning of the next reception activities will exceed the power expended to reinitialize the RF chain's components and registers for the next reception activities. Based on this determination, the device processor may configure the RF chain either to power down fully, as in conventional implementations, or to enter a low-power mode in which power is maintained to the power rails supplying the memory registers storing RF communication data, thereby avoiding the power surge of restarting the registers and part of the power drain associated with writing the communication data back into the registers. In some embodiments, the mobile communication device may be a multi-SIM device.
