Systems and methods for providing local hardware limit management and enforcement |
摘要 |
Systems and methods for providing local hardware limit management and enforcement are described. One embodiment includes a system for managing and enforcing hardware limits on a system on chip (SoC). The system includes a plurality of chip components provided on a system on chip (SoC). A network of local limit manager (LLM) components is distributed on the SoC. Each LLM component is in communication with a corresponding sensor module that monitors one or more of the chip components. Each LLM component comprises a generic hardware structure for enforcing one or more hardware limits associated with the corresponding sensor module. |

1. A method for providing hardware limit management and enforcement, the method comprising:
monitoring a chip component on a system on chip (SoC) with a sensor module; storing sensor data from the sensor module in a local limit management (LLM) hardware component, wherein the sensor data comprises an estimated current consumption of the monitored chip component and wherein the LLM hardware component is associated with a domain limit manager (DLM) component in a parent/child relationship such that the DLM component is configured as a parent component to budget a programmable battery current consumption limit to a child LLM component; storing the battery current consumption limit in the LLM hardware component; comparing the estimated current consumption of the monitored chip component to the battery consumption limit stored in the LLM hardware component; and if the estimated current consumption exceeds the battery consumption limit, initiating a predefined throttling action for enforcing the battery consumption limit. |
