摘要： Data may be loaded in a computing device from a non-volatile storage medium using files having a nested structure. An outer file metadata portion may be read from an outer file on the storage medium into RAM. The outer file may include the outer file metadata portion and an outer file data portion. The outer file data portion may then be read from the outer file on the storage medium into the RAM based on the outer file metadata portion. The outer file data portion may be an inner file. The inner file may include an inner file metadata portion and an inner file data portion. Then, the inner file metadata portion may be read from the inner file in the RAM. The inner file data portion may be read from the inner file in the RAM based on the inner file metadata portion.

摘要： Various embodiments of methods and systems for a power and performance-optimized secure image load boot flow in a specialty metering device (“SMD”) are disclosed. An exemplary method includes a CPU that transitions into an idle state, such as a WFI state, for durations of time during a boot sequence that coincide with processing by a DMA engine. That is, the CPU may “sleep” while the DMA engine processes workloads in response to instructions it received from the CPU.

摘要： A system and a method for power mode selection in a portable computing device is provided herein. The system and method may comprise operations for operating the portable computing device in a normal mode. The normal mode may utilize a plurality of memory banks within a volatile memory, such as a random access memory (“RAM”), where the memory banks are powered-up and operable to store data. The system and method may further identify a memory segment within the plurality of memory banks, store the memory segment as a stored memory segment (where the stored memory segment is operable to restore the memory segment), and power down the powered-up memory bank associated with the memory segment. Further aspects are described herein.
