Profiling and Code coverage on RISC-V using simulation

We recently licensed our Floating point library for RISC-V to a large international corporation. They asked not only for our functional verification suite, but also for a verification of the verification suite. A code coverage report showing that the entire code had been executed. While we know that all lines and every instruction have been […]

SEGGER in times of the coronavirus / COVID-19

The idea of this blog is to give readers a glimpse of the plans and inner workings at SEGGER, what we’re working on, what we’re thinking, what’s going on, and what’s cooking. These days, unfortunately, that includes dealing with the coronavirus. I think everybody by now understands that this virus is not just a regular […]

The SEGGER Compiler

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, […]

Floating-point face-off, part 2: Comparing performance

I used to think that floating-point was not for Embedded Systems. Too slow, too much code overhead and rounding is always a problem. It turns out that while scaled integers still have a performance benefit, floating-point computations can be done with a surprisingly high performance these days on modern Embedded CPUs. This is true not […]

Finding the right (Q)SPI Flash for your project

Not all SPI Flashes are created equal SPI Flashes have become very popular as an inexpensive way to add nonvolatile storage (flash memory) to an Embedded System. They come in various capacities, so increasing memory is fast and easy. Any microcontroller can interface to them via SPI or QSPI peripheral interfaces, or simple general purpose […]

IoT Station#1 Launched (using emMQTT)

Here’s more of “What’s cooking at SEGGER”.  We were looking for a quick and easy way to demonstrate an integration of SEGGER’s software libraries, embOS, emNet, emSSL, emMQTT and the IoT Toolkit, with IoT cloud services, such as Amazon Web Services (AWS). Having the idea, the software, the hardware, and the expertise, all we needed […]

Turning an FPGA into a powerful microcontroller. No external memory required.

FPGAs can do things that CPUs cannot do as quickly, or as efficiently, or simply cannot do at all. The bottleneck on rapidly expanding market usage for a powerful FPGA, with hard CPU cores, is that almost all applications use Linux. This requires a lot of memory, most of all RAM, and insufficient built-in RAM […]

The SEGGER Linker – Replacing the GNU linker

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 […]
