Abstract：Abstract: At present, the performance of Java Virtual Machine in Linux NC is relatively low. This paper came up with an optimization, which based on the Direct Threaded Interpreter, and three extended techniques were designed to stand out the effect of optimization. In this way, considered the conditions of hardware and software, the executing efficiency of Java VM can be upgraded. Besides, this project can also reduce the cost of CPU and memory.
