How expensive in terms of code size are floating-point operations if the CPU does not have an floating-point unit (FPU)? In this article, I will investigate, based on Embedded Studio for ARM and a generic Cortex-M3 device, how big (or small) an entire application using basic float operations, add, sub, mul, and div, can be. […]
When searching on-line for small C-programs, there seems to be a lot of confusion about what is doable and what is not. There are a lot of posts wondering why even for minimal programs such as “Hello world” applications are so big, but not many explanations or fixes. I will show how to make a […]
With the latest Embedded Studio update to version 5 the SEGGER Linker also received new features. One of these features is the new integrity check functionality which I would like to focus on in this article. Supported are numerous CRC and message digest algorithms (e.g. MD5 and SHA).
I decided to put Embedded Studio to the test: How little flash memory could be used on a typical Cortex-M Microcontroller to toggle an LED?
At SEGGER, we use our own tools to establish an internal feedback loop. This is extremely helpful in creating and fine-tuning our products. A significant amount of engineering time and effort is put into making our IDE Embedded Studio better and better, every day. Embedded Studio is easy to download and install, cross-platform, very fast, […]
Things at SEGGER have been slower for the past three months or so. Or at least it may seem like that from the outside. There are two main reasons for this. First, we had a great summer and vacation season in Germany (as in most of Europe). Secondly, we have been busy planning, supervising construction […]
In the previous post, Rolf described some of the progress that we have made on the brand-new SEGGER linker. In this post I examine the gnarly problems with the GNU linker and how they are easily solved by the SEGGER linker. A follow-up post will examine more of the linker’s capabilities.
At SEGGER, we pretty much use our own tools and products to develop our products. That includes using our middleware, such as embOS, emNet, emUSB, emFile, web and FTP Servers and so on, as part of the firmware of our J-Link, J-Trace and Flasher products. And the other way round, utilizing the same hardware products, most […]
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 […]
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 […]
