The execution time of bytecodes, the instructions of the Java virtual machine, is known cycle accurately for Java processor, which simplifies the low-level WCET analysis [1 . In hard real-time systems, the estimation of the WCET is essential. WCET analysis is in general an undecidable problem. As concerning above, we propose some of WCET analysis methods using control flow graph applied for high-level and low-level Java processor. Java bytecode generation has to follow stringent rules in order to pass the class file verification of the JVM. Those restrictions lead to an analysis friendly code; e.g. the stack size is known at each instruction. The control flow instructions are well defined. Branches are relative and the destination is within the same method. Detection of basic blocks in Java bytecode and construction of the control flow graph (CFG) is thus straight forward. 2017-08-11T03:14:44Z 2017-08-11T03:14:44Z 2011 Article 2588-1124 http://repository.vnu.edu.vn/handle/VNU_123/56474 en Vol. 27;No. 2 (2011) application/pdf H. : ĐHQGHN |
