Abstract: A multi-processor system handles interrupts using a power and performance status of each processor and a usage scenario of each processor. The power and performance status is indicated by factors that affect power consumption and processor performance. The system identifies one of the processors for handling an interrupt based on a weighted combination of the factors. Each factor is weighted based on a usage scenario for which the interrupt was generated. The system then dispatches the interrupt to the identified one of the processors.
