This article discusses Hardware Interrupts in Windows and how to show the boot menu in Windows. A video at the MSDN blog shows Windows booting real fast – under seven seconds. The computer used was an ...

A signal created and sent to the CPU that is caused by some action taken by a hardware device. For example, keystroke depressions and mouse movements cause hardware interrupts. See IRQ and interrupt.

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...

If there is an interrupt present then it will trigger the interrupt handler, the handler will stop the present instruction which is processing and save its configuration in a register and load the ...

I thought I had seen this before, but I cannot recall. All of a sudden my wife's Vista box is having "hardware interrupts" use 40% of her CPU, pretty much all the time. It's not listed in task manager ...

A priority interrupt controller is a hardware designed chip which acts as an overall system manager to efficiently handle the multiple interrupts that tend to occur from the varied number of ...
