Performance tuning our software

As you may have noticed, SEGGER have introduced a cryptographic algorithm library, emCrypt. We released this product as existing and new customers wanted to use the “hidden” cryptographic capabilities of emSSL but didn’t need to run SSL/TLS as a protocol. Well, that is not entirely true, some customers already had licenses for emSSL but also wanted a fully-documented, tested and verified cryptographic library for other parts of their secure systems with additional algorithms that are not offered as part of emSSL.

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 […]

Profiling software in Embedded Systems

Good engineers for embedded software strive to write software that is efficient, small, and maintainable. However, inefficiencies can appear from the most unexpected places, places that you would never think to look for a performance bottleneck or “sinkhole”. This short article describes different ways to profile an application, showing the path to identifying such a sinkhole […]

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 […]
