Hardware interrupts are used by devices to communicate that they require attention from the operating system. Internally, hardware interrupts are implemented using electronic alerting signals that are sent to the processor from an external device, which is either a part of the computer itself, such a...

A hardware interrupt is a signal that indicates the occurrence of an asynchronous event in a computer system. It causes the CPU to pause its current task, save its state, and process a new request before returning to the previous task. ...
In subject area:Computer Science An interrupt function in computer science refers to a mechanism that interrupts the processor to gain access to either DOS or BIOS functions. It is used to interact with hardware through BIOS functions and manage program execution through DOS functions. ...
This description should satisfy most readers, although someone with a taste for hardware and some experience with her computer might be interested in going deeper. If you don’t care about the internal details, you can skip to the next section. ...
In addition to external interrupts, the interrupt architecture of the present invention supports inter-processor interrupts (IPIs) by which any processor may interrupt itself or one or more other processors in the NUMA computer system. IPIs are triggered by writing to memory mapped registers in ...
Implementation of priority interrupt controller for the computing system with open architecture Traditional Micro-Controller Unit (MCU) usually uses daisy chain interrupt hardware. It is much a waste of time that MCU polls interrupt sources according ... IA Klimenko,NA Sakara,MV Fedorchuk 被引量: ...
The kernel is using the IRQ line while performing a hardware device probe. IRQ_WAITING The kernel is using the IRQ line while performing a hardware device probe; moreover, the corresponding interrupt has not been raised. IRQ_LEVEL Not used on the 80 × 86 architecture. ...
