Abstract
An interrupt-notification control unit that receives interrupt requests from a plurality of interrupt dispatchers and sends the received interrupt requests together to a processor, where the interrupt-notification control unit determines a correlation among the interrupt requests to control a time to send the interrupt requests together to the processor.
Claims12
An interrupt-notification control unit that receives interrupt requests from a plurality of interrupt dispatchers and sends the received interrupt requests together to a processor, and
- wherein the interrupt-notification control unit determines a correlation among the interrupt requests to control a time to send the interrupt requests together to the processor.
A semiconductor integrated circuit comprising:
- a processor;
- an interrupt-notification control unit that receives interrupt requests from a plurality of interrupt dispatchers and sends the received interrupt requests together to the processor;
- and
- a peripheral macro connected with the processor;
- wherein the interrupt-notification control unit determined a correlation among the interrupt requests to control a time to send the interrupt requests together to the processor.
A method of controlling interrupt requests, comprising:
- aggregating a plurality of interrupt requests based on a determination of whether the interrupt requests match a condition;
- and
- transmitting the aggregated interrupt requests collectively to a processor.
