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...

Minimal skew clock embedding considering time variant temperature gradient
The existing temperature-aware clock embedding assumes a time-invariant temperature gradient. However, it is not solved how to find the worst-case temperature gradient leading to...

Efficient longest executable path search for programs with complex flows and pipeline effects
Current development tools for embedded real-time systems do not efficiently support the timing aspect. The most important timing parameter for scheduling and system analysis is th...

Towards a Flow Analysis for Embedded System C Programs
Reliable program Worst-Case Execution Time (WCET) estimates are a key component when designing and verifying real-time systems. One way to derive such estimates is by static WCET ...
