Abstract: Reconfigurable shared memory systems, and related processor-based systems and methods are disclosed. The reconfigurable shared memory system can be included in a processor-based system to provide memory for data storage. In exemplary aspects, the reconfigurable shared memory system not only includes the dedicated memory and the general memory (e.g., system cache memory), but also includes a reconfigurable memory. The reconfigurable memory can be configured as either part of addressable memory space of the dedicated memory if an application requires such additional dedicated memory, and/or configured as part of the addressable memory space of the general memory to provide additional memory to other clients for increased processing performance if such reconfigurable memory is not needed as part of the dedicated memory. The dedicated memory does not have to be sized to the worst-case size requirements of a given application.

Abstract: In some aspects, the present disclosure provides a method for managing a command queue in a universal flash storage (UFS) host device. The method includes determining to power on a first subsystem of a system-on-a-chip (SoC), wherein the determination to power on the first subsystem is made by a second subsystem of the SoC based on detection of user identity data contained in a first image frame during an initial biometric detection process. In certain aspects, the second subsystem is configured to operate independent of the first subsystem and control power to the first subsystem. In certain aspects, the second subsystem includes a second optical sensor, a set of ambient sensors, and a second processor configured to detect, via a set of ambient sensors, an event comprising one or more of an environmental event outside of the device or a motion event of the device.
