Abstract
Research in Worst-Case Execution-Time (WCET) analysis aims at integrating WCET analysis with program compilation, thus increasing compiler complexity and forcing real-time software developers to use specific compilers. This paper describes a simple approach to WCET analysis that is not compiler-specific: A software tool reads the path information contained in source programs and maps this information onto the respective assembler programs. A low-level WCET analysis tool then computes detailed timing information of the annotated assembler programs, and passes the information back to the source level. Experiments demonstrate the feasibility of the approach.
