High-performance timing simulation of embedded software

Content Provider	ACM Digital Library
Author	Bringmann, Oliver Viehl, Alexander Schnerr, Jürgen Rosenstiel, Wolfgang
Abstract	This paper presents an approach for cycle-accurate simulation of embedded software by integration in an abstract SystemC model. Compared to existing simulation-based approaches, we present a hybrid method that resolves performance issues by combining the advantages of simulation-based and analytical approaches. In a first step, cycle-accurate static execution time analysis is applied at each basic block of a cross-compiled binary program using static processor models. After that, the determined timing information is back-annotated into SystemC for fast simulation of all effects that can not be resolved statically. This allows the consideration of data dependencies during run-time and the incorporation of branch prediction and cache models by efficient source code instrumentation. The major benefit of our approach is that the generated code can be executed very efficiently on the simulation host with approximately 90% of the speed of the untimed software without any code instrumentation.
