Getting printf Output from Target to Debugger

  Erich Styger recently posted a great tutorial on how to add console functionality using Single Wire Output (SWO) on ARM Cortex-M targets. This inspired me to write a more general post on debug output (“printf”) implementations on embedded target, including SWO and RTT. Debug Output from a Target There are different methods to get debug output from the […]

Update on: Comparing Performance on Windows, Linux and OS X

If you haven’t read the original post, have a look at it: Comparing Performance on Windows, Linux and OS X I got my computer upgraded 🙂 It is very tiny, an Intel NUC Kit. But what matters is what is inside: An Intel i7 with 4 cores and hyper-threading, so like 8 processors, 16 GB […]

Why you should benchmark your embedded system

There are plenty of potential reasons why an embedded system may not deliver the full CPU performance. This is not even that easy to detect, so here is a way to check if your system gives you the performance you expect. What can go wrong? Today’s embedded systems are complex computers. Microcontrollers are usually easiest […]

Comparing Performance on Windows, Linux and OS X

Last week, I compared the speed of the 64-bit and the 32-bit build of Embedded Studio and the GCC compiler. The 64-bit version was the clear winner, with a performance gain of about 5 – 20%. But what can we get from working with different operating systems? At SEGGER, we developers are free to select the operating system […]
