Every byte counts – Smallest “Hello world”

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 […]

Debugging the dual-core NXP i.MX RT600 with the one and only SEGGER J-Link

The i.MX RT600 MCU family from NXP is an interesting one. Not only do the i.MX RT600 devices feature a 300-MHz Arm Cortex-M33 processor core, but they also include a 600-MHz Cadence Tensilica HiFi4 DSP processor core. This makes the i.MX RT600 devices very suitable for audio playback and voice user interface applications. However, having […]

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 […]

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 […]

Current state of the trace market

When talking about tracing, you will mostly hear about the approach on the software side on how the trace data gets analyzed and all the associated benefits. But what about the hardware and any possible limitations? The different trace types Generally speaking, trace is an advanced debugging technique that offers the user a link between […]

The SEGGER linker and SOMNIUM assets

Startups come and go, some make it, some don’t. The embedded tools market is especially tough even for those that know it well, and being able to innovate and be successful needs true insight. To cut to the chase, SEGGER have acquired all intellectual property assets of SOMNIUM Technologies.
