Abstract
Provided are an apparatus and a method for controlling an interrupt rate for a processor based on processor utilization. Accordingly, it is possible to improve an I/O response latency and improve energy efficiency.
Claims16
An interrupt control apparatus comprising:
- a power management governor configured to monitor a power state of a processor executing an application involving an I/O load for a peripheral device;
- and
- an interrupt controller configured to control an interrupt rate generated by the peripheral device for the processor based on the power state of the processor,
- wherein the interrupt controller is configured to control the interrupt rate according to a change in the power state of the processor corresponding to a utilization of the processor while the application is being executed.
