In this paper, vve propose a solution for a worstl-case execution time (WCET) analyzable Java system - a combination of a time predictable Java processor and a method WCET analysis at Java bytecode level. 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 rul...
