Presentation Transcript

  1. Design for Predictability and Efficiency(PREDATOR) • Reinhard Wilhelm • Saarland University • Saarbrücken, Germany

  2. Outline • Objectives of PREDATOR • Overall Structure of PREDATOR • The Work Packages • Starting Points of our Work • Interactions between WPs • Milestones and deliverables • Expected activities of PREDATOR • Project management

  3. Motivation • Design of Real-Time Systems: • Gap average-case  worst-case behavior increases • Static analyses: derive guarantees about worst-case behavior • Tightness of guarantees: Product of Uncertainty x Penalties • Predictability vs. Efficiency: Past systems were… • either predictable, but inefficient (no caches, pipelines, over-provisioning of resources, …), • or efficient, but unpredictable (caches, deep pipelines, branch prediction, speculation, …) • PREDATOR: Reconcile Predictability and Efficiency

  4. Objectives of PREDATOR • Overall Goals of PREDATOR: • Reduce Uncertainty by increasing system analyzability • Reduce Penalties by influencing system design • Objectives: • Improve design & development methods for real-time systems • Develop tools supporting such development methods • Develop architectural concepts supporting timing analysis • Approach: • Synergetic development of tools with design • Predictability vs. efficiency: Multi-objective optimization problem • Resource-aware abstraction during system design

  5. PREDATOR Partners • Saarland University (Coord.): R. Wilhelm • ETH Zürich: L. Thiele • TU Dortmund: P. Marwedel • Alma Mater Stud.-Università di Bologna: L. Benini • Scuola Superiore Sant’ Anna, Pisa: G. Buttazzo • AbsInt GmbH, Saarbrücken: C. Ferdinand • EADS Airbus, Toulouse: B. Triquet • Robert Bosch GmbH, Stuttgart: O. Rogalla
