SoC Domain Throttling Priority Order for Power and Thermal Limits

The throttling mechanism is extended from computing IP blocks to non-computing IP blocks, making the power management system universal across all domain controllers in the SoC. This allows a single throttling framework to manage power consumption across diverse component types (CPU, GPU, display, audio, etc.), improving overall power budget management without requiring separate mechanisms for each block

The SoC is divided into multiple domains, each with its own domain controller that independently manages throttling for specific IP blocks. This segmentation allows distributed power management where each domain controller handles only its assigned blocks, reducing the complexity burden on any single controller while achieving system-wide power management

Throttling priorities are assigned to each domain controller in advance, establishing a predetermined throttling order before power constraints are violated. When power or thermal limits are approached, the system follows this pre-established priority sequence to throttle domains, ensuring reliable adherence to constraints without requiring complex real-time decision-making algorithms

Each domain controller autonomously monitors its own power consumption and thermal conditions, and independently executes throttling decisions for its assigned IP blocks based on its priority level. This self-service approach allows distributed control where each domain manages itself according to the global priority framework, reducing the need for complex centralized control mechanisms
