Multithreaded models improve the efficiency of parallel systems by combining inner parallelism, asynchronous data availability with the locality of von Neumann model. This model executes thread code which is generated by compiler and of which quality is decided by the method of generation. But multithreaded models have the demerit that execution model is restricted to a specific platform. On the contrary, Java has the platform independency, so if threads code is translated into Java bytecode, the characteristics of multithreaded models can be used without being changed in many platforms. Java executes Java language in the system of Java virtual machine by changing a source language into bytecode, a kind of intermediate language format. Java bytecode plays a role of an intermediate language in translator and Java virtual machine works as back-end in translator. This paper aims to execute multithreaded code in java virtual machine, so that multithread code may have the independent characteristics in platform. Design and implementation of translator which translate from thread code of multithreaded model to Java bytecode will be made, and execution of Java virtual machine analyzed.
