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 ...

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 ...

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 ...

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 ...

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 ...
