MEASURING SYSTEM AND METHOD OF WORST-CASE EXECUTION TIME USING TEST TECHNIQUES

摘要

The present invention relates to a system and method for measuring the worst execution time of a real time program using a cycle table and a test case together. The system for measuring the worst execution time includes: a cycle table generation unit for generating a cycle table by analyzing a relationship between a source code of a first real-time application program and a corresponding assembly instruction; a program code analyzer for analyzing the source code of the second real-time application program; a program code extension unit for inserting the required cycle calculation code and route identification probe code into the source code of the second real-time application program; a test case generation unit for generating a test case based on a result of analyzing a control flow of the second real-time application program; a program execution unit for executing the second real-time application program based on the generated test case and storing the required time for each execution path; and a worst execution time extraction unit for extracting a longest execution time among the required execution time for each stored execution path.
