A story heard thousands of times “Software complexity is increasing” — I’m sure this is not the first time, nor will be the last time you read this claim. It may sound rhetorical, but repeatedly claiming overtime that software complexity is increasing is nothing but a concrete observation about the incessant pace with which several technological domains are evolving thanks…

"Verified Lustre normalization with node subsampling" by Timothy Bourke, Basile Pesin, Paul Jeanmaire, and Marc Pouzet is the best paper winner of the International Conference on Embedded Software (EMSOFT) in 2021. This blog post gives an overview of the work. The Coq development described in the paper is available online. There is also a page of links between the article…

Introduction Welcome back to a second hands-on blog post in which we explore the implementation of classic real-time concepts in POSIX operating systems. In a previous post, we examined the classic periodic task abstraction and how to implement it in Linux. This time around, let’s explore its equally well-known counterpart: the sporadic task model for event-driven workloads. As we'll compare…

In July, we held another successful ECRTS, with high quality papers, great sense of community, novel concepts, and the same spirit as in previous years. Behind the scenes, however, significant changes happened. The group of persons responsible for the development and organization of the conference, the Executive Board of the Technical Committee of Real-time Systems of Euromicro, has changed, and…

Take 100 lines of C code and a hardware platform. How long will it take for the hardware to execute the code? Being able to construct an answer to this question in the scope of real-time systems is akin to solving one of the Millenium Prize Problems. Of course, the first instinct is to wonder if any loop in the…

About two years ago, as new members of the SIGBED executive committee (EC), we decided to replace the SIGBED review with a blog that could serve as an informal medium for the SIGBED community. After receiving input from the SIGBED EC members and months of preparation, we finally launched the blog in April 2020. So far, the blog has published…

In RTAS 2021, we organized a panel discussion on “RTOS for Autonomous Machines”. The panelists are Shinpei Kato (The University of Tokyo & Tier IV, Inc.), Andrei Kholodnyi (Wind River Systems), Shaoshan Liu (PerceptIn), Jan Staschulat (Robert Bosch GmbH), and Richard West (Boston University). An interesting topic discussed during the panel is “Will there be something analog to Android for…

Formal verification of cyber-physical systems (CPS) requires reasoning methods for not just software, but also analyzing how the physical side of the system will behave. As the laws of nature are written in differential equations, CPS formal verification researchers have inevitably needed to create analysis methods that can analyze systems with differential equations. For example, the behavior of an…

This article argues that a key new frontier for the real-time systems research community lies in developing the architectural and algorithmic foundations of real-time artificial intelligence. As always, by “real-time” we do not mean fast (or “streaming”), but rather “with a capability to respond predictably to different urgency (and criticality) requirements”. A key challenge in modern AI is perception. Machine…
