Abstract: 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.

Abstract: In some aspects, the present disclosure provides a method for managing applications in flash memory devices. In one example, an application manager is configured to manage data stored in an application partition of a flash memory device. The application manager may be configured to receive a request from an application processor to read a first application data stored on the application partition of the flash memory device partitioned into the application partition and a second partition, and manage one or more applications stored on the first partition according to a physical block mapping of the one or more applications.
