Abstract
The present invention system and method enables dynamic reconfiguration of an electronic device with appropriate interrupts in a convenient and efficient manner. A plurality of internal peripherals, an interconnecting component and the external coupling ports are programmably configurable to perform a variety of functions with different interrupts. In response to interrupt request names that are utilized in multiple configurations, an interrupt dispatcher component directs operations to an appropriate interrupt handler for a particular configuration based upon both the configuration image and the interrupt service request indicator. The electronic device can be automatically reconfigured based upon the existence of a predetermined condition by activating different configuration images and associated interrupts are automatically included. Pending interrupt state indicators are resolved (e.g., deleted) during the reconfiguration.
