Summary

TACLe is a four years lasting COST Action funded by the COST Office in Brussels.

Many embedded systems are safety-critical real-time systems that must process data within given deadlines. To validate real-time properties, timing analyses of program code are mandatory. Research on techniques for timing analysis of software touches many areas within computer science, e.g., computer architecture, compiler construction and formal verification.

This COST Action aims to cross-link the leading European researchers in these areas and thus to strengthen Europe's leading position in the field of timing analysis. TACLe's research activities include timing models for multicore systems, support of timing analysis by software development tools, early-stage timing analysis right in the beginning of the software development cycle, and the consideration of resources other than time like, e.g., energy dissipation.

Abstract: In hard real-time multitasking systems, applying WCET-oriented code optimizations to individual tasks may not lead to optimal results with regard to the system's schedulability. We propose an approach based on Integer-Linear Programming which is able to perform schedulability aware code optimizations for periodic task sets with fixed priorities. We evaluate our approach by using a static instruction SPM optimization for the Infineon TriCore microcontroller.
