Abstract: Micro-idle power in a subsystem of a portable computing device may be actively managed based on client voting. Each client vote may include a client activity status indication and a client latency tolerance indication. Votes are aggregated to provide an aggregate client latency tolerance, which may be used to obtain a set of micro-idle time values. Micro-idle timers in the subsystem may be set to associated micro-idle time values. The micro-idle timers determine whether one or more of the micro-idle time values have elapsed. A power management policy associated with each micro-idle time value determined to have elapsed may be applied to a portion of the subsystem.

Abstract: Systems and methods are disclosed for configuring dynamic random access memory (DRAM) in a personal computing device (PCD). An exemplary method includes providing a shared command access (CA) bus in communication with a first DRAM and a second DRAM. A first command from a system on a chip (SoC) is received at the first DRAM and the second DRAM. A decoder of the first DRAM determines whether to mask a mode register write (MRW) in response to the received first command. A second command containing configuration information is received vie the shared CA bus at the first DRAM and the second DRAM. Responsive to the determination by the decoder of the first DRAM, the received. MRW is either ignored or implemented by the first DRAM.

Abstract: Various embodiments of systems and methods are disclosed for reducing volatile memory standby power in a portable computing device. One such method involves receiving a request for a volatile memory device to enter a standby power mode. One or more compression parameters are determined for compressing content stored in a plurality of banks of the volatile memory device. The stored content is compressed based on the one or more compression parameters to free-up at least one of the plurality of banks. The method disables self-refresh of at least a portion of one or more of the plurality of banks freed-up by the compression during the standby power mode.

Abstract: A method and system for managing safe downtime of shared resources within a portable computing device are described. The method may include determining a tolerance for a downtime period for an unacceptable deadline miss element of the portable computing device. Next, the determined tolerance for the downtime period may be transmitted to quality-of-service (“QoS”) controller. The QoS controller may determine if the tolerance for the downtime period needs to be adjusted. The QoS controller may receive a downtime request from one or more shared resources of the portable computing device. The QoS controller may determine if the downtime request needs to be adjusted. Next, the QoS controller may select a downtime request for execution and then identify which one or more unacceptable deadline miss elements of the portable computing device that are impacted by the selected downtime request.
