Precision Timed Computing in the Synchronous Setting

Abstract:

Design of time critical embedded systems is usually based on the theory of real-time systems. While such theory is sound, the implementation of such systems on speculative processors leads to many possibilities of errors. In this talk, we propose an alternative approach based on Precision Timed (PRET) architectures. PRET architectures guarantee precise timing without sacrificing throughput. I will focus on a recent synchronous C variant called PRET-C for programming PRET architectures. We map logical time in PRET-C to physical time using static timing analysis. Benchmarking results show that the proposed approach provides a scalable and efficient mechanism for realizing precision timed systems.
