Hierarchical power management for multi-device ar systems
The patent US12072752B2 describes an artificial reality system that includes a device capable of generating or displaying artificial reality content. This system comprises a host subsystem and multiple non-host subsystems, each equipped with a local processor and a child energy processing unit (EPU). The host subsystem is responsible for managing the power states of the non-host subsystems. It determines when a non-host subsystem should be powered up based on the status of its corresponding power domain. Upon this determination, the host subsystem generates a reset vector and sends it to the non-host subsystem, prompting its local processor to initiate a cold boot sequence.
Further claims detail the operational intricacies of the system, including the use of control and status registers, the management of multiple power domains within each non-host subsystem, and the interaction between the child EPU and a top-level clock from the host subsystem. The child EPU can request a default clock, and upon receiving a clock acknowledgment, it can activate additional power domains. The host subsystem also monitors the power status of the local processor to ensure proper functioning. The patent outlines a method for powering up non-host subsystems and initiating their operational sequences, emphasizing the system's structured approach to managing energy and processing resources in artificial reality applications.
