Abstract: Circuits and methods for power dependent selection of boot images are disclosed. In an example implementation, an apparatus includes a memory circuit and a processor disposed on an integrated circuit die. The processor is configured to retrieve and execute instructions from the memory circuit. The apparatus also includes a power management circuit configured to determine a value indicative of an amount of power available to power the IC die. A boot loader circuit is coupled to the power management circuit and is configured to select one of a plurality of boot images based on the determined value indicative of the amount of power available. The boot loader circuit loads a set of instructions included in the selected one of the boot images into the memory circuit and enables the processor to execute the set of instructions.
