SEGGER’s J-Trace PRO streaming trace probe and Ozone debugger make a great team. One highlight of this symbiotic relationship is the Timeline window. It allows users to correlate and visualize data sampling, current consumption, and program execution in one combined signal plot. This article takes a closer look at this functionality.
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 […]
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 […]
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 […]
This posting continues to explore the performance of floating point and how microcontrollers can efficiently execute basic floating-point operations.
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 […]
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 […]
What makes a great runtime library different from a run-of-the-mill runtime library? This article will answer some of those questions with hard data and technical insights.
One of the things that irritates me a lot is manual work that should be automated by machines. Automation always trumps the error-prone human and, in my case, offered the opportunity to get to use some of SEGGER”s software I’d never used before to develop a useful tool.
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 […]
