Sinopsis

In contrast to general-purpose systems, the correctness of real-time systemsnot only depends on the logical results of the computation but also on itstemporal behavior specified by the worst-case execution time (WCET). Nowadays,software for embedded systems acting as real-time systems is writtenin high-level languages requiring the presence of a compiler. Modern compileroptimizations aim at reducing the program?s average-case executiontime completely ignoring the WCET. Tuning an application with respect to itsworst-case execution time must be performed manually. To avoid this tediousand error-prone approach, an automation by the compiler is highly desired.This book faces this issue and describes the integration of a timing analyzerinto a compiler infractructure. It presents flexible concepts describing thedesign and realization of a novel WCET-aware C compiler. Due to thecombination of the extensive compiler knowledge on the program and thetiming information, this compiler framework is best suited for the developmentof WCET-aware compiler optimizations. This book is intended forstudents but also for any reader interested in the construction of real-timecompilers.
