Power budgeting refers to the process of allocating and managing the power consumption of electronic devices, systems, or networks in order to optimize energy efficiency and ensure reliable operation. This involves estimating the power requirements of different components, setting power limits, and monitoring power usage to prevent overload or inefficiency. Power budgeting is important for reducing energy costs, extending battery life, and minimizing environmental impact in electronic systems. It is particularly critical in portable devices, data centers, and other applications where power consumption is a major concern.
