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.

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 ...

I've recently felt my computer getting slower after an extended period of usage, thus have set out to investigate what was up. Using the sysinternal process explorer, i have discovered that what is ...

This is very strange: on my newer machine (just a few months old) I get occasional bouts of high CPU usage due to hardware interrupts (as reported by Process Explorer). The weird part is how it's so ...

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 ...

We love interrupts in our microcontroller projects. If you aren’t already convinced, go read the first installment in this series where we covered the best aspects of interrupts. But everything is not ...
