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.
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 ...
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 ...
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 ...
Linux is well tuned for throughput-limited applications, but it is not well designed for deterministic response, though enhancements to the kernel are available to help or guarantee determinism.
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 ...
This hardware/software combination lets OSes offload all TCP/IP traffic to the specialized hardware. TCP/IP has long been the common language for network traffic, and recent initiatives such as ...
As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...
What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...
