Running Linux Applications In An Embedded, Real-Time Environment

Filed under
Software

Following its success in the server market, Linux is generating a lot of interest as the new OS of choice in embedded and real-time devices. However, because the Linux kernel was not originally designed for these types of applications, it faces a number of interesting technical challenges that must be over-come if it is to gain widespread acceptance in this market. This paper starts with a discussion of the architectural features of the Linux kernel, with particular emphasis on showing where there is a good match with the requirements of the embedded market and where problems exist. The paper then goes on the present a comparison of the different approaches that have been used to adapt Linux for real time and embedded systems.

Linux is the rising star among operating sys-tems. Mergers, IPOs and surging growth have catapulted Linux from the comfortable realms of Universities and research labs into the bright lights of the business world at breakneck speed. Windows assailant, Unix saviour, the reasons for Linux success in the server market are as many as they are diverse.

Can Linux succeed where others have failed?

  • Cura, the nice 3D print slicer, is now in Debian Unstable
    After several months of working and waiting, I am happy to report that the nice and user friendly 3D printer slicer software Cura just entered Debian Unstable. It consist of five packages, cura, cura-engine, libarcus, fdm-materials, libsavitar and uranium. The last two, uranium and cura, entered Unstable yesterday. This should make it easier for Debian users to print on at least the Ultimaker class of 3D printers. My nearest 3D printer is an Ultimaker 2+, so it will make life easier for at least me. :)

  • Mozilla releases tools and data for speech recognition
    Voice computing has long been a staple of science fiction, but it has only relatively recently made its way into fairly common mainstream use. Gadgets like mobile phones and "smart" home assistant devices (e.g. Amazon Echo, Google Home) have brought voice-based user interfaces to the masses. The voice processing for those gadgets relies on various proprietary services "in the cloud", which generally leaves the free-software world out in the cold. There have been FOSS speech-recognition efforts over the years, but Mozilla's recent announcement of the release of its voice-recognition code and voice data set should help further the goal of FOSS voice interfaces. There are two parts to the release, DeepSpeech, which is a speech-to-text (STT) engine and model, and Common Voice, which is a set of voice data that can be used to train voice-recognition systems. While DeepSpeech is available for those who simply want to do some kind of STT task, Common Voice is meant for those who want to create their own voice-recognition system—potentially one that does even better (or better for certain types of applications) than DeepSpeech.
  • FreeBSD-Based TrueOS 17.12 Focuses on Faster Boot, Bhyve and LibreSSL Support
    en Moore, the creator of the FreeBSD-based TrueOS computer operating system and Lumina desktop environment, released the TrueOS 17.12 update, which introduces multiple enhancements. Synced with the FreeBSD 12.0-CURRENT and FreeBSD ports tree software repositories as of December 4 and November 30, 2017, respectively, TrueOS 17.12 is an incremental update to the operating system adding improvements to the OpenRC-based boot process, removable-device management, LibreSSL and SysAdm API integrations, as well as Bhyve support for TrueOS Server Install. "We have also been working quite a bit on the server offering of TrueOS, and are pleased to provide new text-based server images with support for Virtualization systems such as bhyve," said Ken Moore in the release announcement. "This allows for simple server deployments which also take advantage of the TrueOS improvements to FreeBSD."
