With the growing complexity of embedded systems software, high code quality can only be achieved using a compiler. Sophisticated compilers provide a vast spectrum of various optimizations to improve code aggressively w.r.t. different objective functions, e.g. average‐case execution time (ACET) or code size. Owing to the complex interactions between the optimizations, the choice for a promising sequence...
In the past decades, embedded system designers moved from simple, predictable system designs towards complex systems equipped with caches, branch prediction units and speculative execution. This step was necessary in order to fulfill increasing requirements on computational power. Static analysis techniques considering such speculative units had to be developed to allow the estimation of an upper...
Caches are widely used to bridge the increasingly growing gap between processor and memory performance. They store copies of frequently used parts of the slow main memory for faster access. Static analysis techniques allow the estimation of the worst case cache behavior and enable the computation of an upper bound of the execution time of a program. This bound is called worst-case execution time (WCET)...
