Background | Real-Time Systems
Real-time schedulability analysis for any hard real-time system requires the WCET to be known beforehand and safely bounded. This is so that the feasibility of scheduling a task set can be determined given a scheduling policy.

Various approaches to determine the WCET of tasks exist, such as :
  • experimental methods, which are considered unsafe or constrained to probabilistic analysis.
  • Static analysis methods to derive safe WCET estimates.
Static methods model hardware components, e.g., the processor pipeline, caches, etc. They model the flow of code through various hardware components and use inter-procedural program representation and longest control-flow paths to obtain an upper bound on the number of cycles for any execution.
