| Abstract(in English) | In recent years, an embedded system often offered Java Virtual Machine implementation. Because, the Java Language Specification has the advantage of the portability, safety and object-oriented. Generally Java applications are executed on interpreters called JavaVM running as a task of an OS and processing such as garbage collection, dynamic class loads. Because of these processes, behavior of the Java threads are difficult to predict and schedule deadlines for real-time processing of Java threads and also the whole system become difficult. These is the problem increasing overhead with the communication and exclusive operation between JavaVMs implemented as one real-time naitive OS's task executing on Java thread. Thereupon, we studied some kainds of methods to run Java threadsin this paper. It did the green thread method, one native task that manages many Java threads with one JavaVM. Another method is one Java thread equal to one OS's task with one JavaVM. Each method is implemented with WabaVM. And, proposing the direct thread method that calls kernel directly, to decreas to this overhead it did implementation on WabaVM similarly. As a result, about 38% of troubles of Java thread generation, deletion are able to be decreased. |
