About OPERA

The design of Real-Time and Embedded Systems is, by definition, subject to constraints:

  • timing of the input, output, or both;
  • minimal quality of the delivered output/service;
  • limited energy, power, or processing/communication resources, and more.

The design space exploration is often driven by expert designers who make the design decisions based on their experience. Such a design phase, however, can be more systematically modeled as an optimization problem, as long as the goal of the design becomes a cost to be minimized. This enables the usage of standard solvers of optimization problems.

The complexity of such a phase, however, is affected by several dimensions, including:

  • the size of the problem (e.g. the sample automotive application of the WATERS 2017 challenge composed by ~1000 functions and ~10000 shared variables);
  • the accuracy of the model for the workload and the computing platform;
  • the tolerable degree of approximation of the constraints.

Fundamentally, the nature of the design problem as described above never changed over time. Today, however, the rise of ML/AI methods as universal tools to solve optimization problems (and any other problem) without any guarantee on the quality of the solution, is challenging the sound practice of addressing the design phase with optimization.

This workshop aims at being a venue in which researchers from the academia and industry working on real-time constraints, design-space exploration, complexity and optimization, meet to share ideas, problems, and solutions.
