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

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
