Abstract

Research in Worst-Case Execution Time (WCET) analysis aims at integrating WCET analysis with program compilation. This integration increases compiler complexity and forces 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.
