Abstract
A process for managing interrupts, which may be performed using electronic circuitry, includes: receiving interrupts bound for a processing device, where the interrupts are received from hardware devices that are configured to communicate with the processing device; generating data containing information corresponding to the interrupts; and sending the data to the processing device.
Claims18
A method performed by electronic circuitry, comprising:
- receiving interrupts bound for a processing device, the interrupts being received from different hardware devices that are configured to communicate with the processing device;
- generating data containing information corresponding to the interrupts, wherein generating comprises aggregating the interrupts in a single data packet;
- and
- sending the data packet to the processing device.
1 more element
Electronic circuitry comprising:
- an input interface for receiving interrupts bound for a processing device, the interrupts being received from different hardware devices that are configured to communicate with the processing device;
- a data generator for generating data containing information corresponding to the interrupts, wherein generating comprises aggregating the interrupts in a single data packet;
- and
- an output interface for sending the data packet to the processing device.
1 more element
A system comprising:
- a processing device;
- one or more first dedicated lines for transmitting first interrupts having a first latency;
- one or more second dedicated lines for transmitting second interrupts having a second latency that is different from the first latency, interrupts on the second lines being multiplexed for transmission;
- and
- circuitry to receive the first interrupts and the second interrupts, to generate a data packet corresponding to the first interrupts and the second interrupts, and to send the data packet to the processing device, wherein generating comprises aggregating the first and second interrupts in the data packet, the data packet being a single data packet.
