One of the issues faced by RISC-V developers is that the code density of the RISC-V instruction set for deeply embedded processors does not match that of Cortex-M with existing tools. That is changing with the product innovations SEGGER have developed, such as the recently-announced SEGGER Linker, capable of reducing code size by up to […]
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?
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 […]
AppWizard is a great tool for designing GUIs with our emWin embedded graphics library. Features like the intuitive editor, the integrated resource management, and the ability to add behavior to the screen objects by adding interactions make it easy to get started with emWin. But you can create even more advanced graphics solutions by extending […]
Recently, we at SEGGER released AppWizard, our new GUI design tool for our emWin embedded graphics library. It is now available as part of the emWin PRO package (v6.10 and later). In Part I of this blog article, I showed how to create a very common type of gauge – a circular gauge – by […]
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 […]
Recently, we at SEGGER released AppWizard, our new GUI design tool for our emWin embedded graphics library. It is now available as part of the emWin PRO package (v6.10 and later). The initial version of AppWizard contains a variety of objects and widgets, such as sliders, rotaries, images, switches, buttons, and more. Getting started with […]
