Automatic Deriving Program Flow Information for the WCET Analysis Based on Abstract Interpretation

Meng-Luo Ji

Abstract

interpretation is used to propagate the variable value range information. Based on the result of the analysis, this paper presents a new method to automatically compute the maximal count of iterations of the loops and to identify the infeasible paths in the loops. This method facilitates the accurate calculation of Worst-Case Execution Time (WCET).
