Objective

There is an ever-increasing demand both for new functionality and for reduced development and production costs for all kinds of Critical Real-Time Embedded (CRTE) systems (safety, mission or business critical). Moreover, new functionality demands can only be delivered by more complex software and aggressive hardware acceleration features like memory hierarchies and multi-core processors. However, these greatly increase system complexity, making it much more difficult to analyze applications for their temporal behavior. Another key problem of CRTE systems is the need to prove that they operate correctly, satisfying all temporal constraints.

The current generations of platforms, despite being based on comparatively simple and old processor technologies, are already extremely difficult to analyze for their temporal behavior, and resulting errors in operation, cost EU industries billions of Euros annually in warranty and post-production costs. The PROARTIS thesis is that the timing behavior of systems that use advanced hardware features like multi-core CPUs and complex memory hierarchies can be analyzed effectively by probabilistic timing analysis techniques that reduce the risk of temporal pathological cases to quantifiably negligible levels. Preliminary research results in cache replacement policies by members of the PROARTIS consortium strongly support this claim.

PROARTIS defines new hardware and software architecture paradigms based on the concept of randomization that, with minimal changes to current processes and methods, guarantee timing behaviors that can be analyzed with probabilistic techniques. PROARTIS uses a holistic approach in which probabilistic analysis extends from hardware design, compiler and real time operating system to applications. On top of this platform, we will build probabilistic timing analysis methods based on current commercial tools. We will validate our approach via an industrial case study.
