Obstacles in Worst-Case Execution Time Analysis
The analysis of the worst-case execution time (WCET) requires detailed knowledge of the program behavior. In practice it is still not possible to obtain all needed information aut...

Bounding Worst-Case Response Time for Tasks with Non-Preemptive Regions
Real-time schedulability theory requires a priori knowledge of the worst-case execution time (WCET) of every task in the system. Fundamental to the calculation of WCET is a schedu...

A Tool for Automatic Flow Analysis of C-programs for WCET Calculation
Bounding the Worst Case Execution Time (WCET) of programs is essential for real-time systems. To be able to do WCET calculations, the iteration bounds for loops and recursion must...

Using Trace Scratchpads to Reduce Execution Times in Predictable Real-Time Architectures
Instruction scratchpads have been previously suggested as a way to reduce the worst case execution time (WCET) of hard real-time programs without introducing the analysis issues p...

Context-Sensitivity in IPET for Measurement-Based Timing Analysis
Abstract. The Implicit Path Enumeration Technique (IPET) has become widely accepted as a powerful technique to compute upper bounds on the Worst-Case Execution Time (WCET) of time-...
