Java translation scheme for consumer electronics home networks

Java is considered to be a promising architecture for use in distributing and running programs on consumer electronics according to the progress of a home network. However, as conventional Java requires a large amount of memory and a highly efficient CPU in appliances running virtual machines, it has been difficult to apply it to the consumer electronics field where low cost and low power consumption are prime concerns. In this paper, we propose a Java translation scheme in which a bytecode-to-bytecode translator for a compact virtual machine is implemented in the home gateway located between an internal home network and external networks. As a result, we have been able to obtain a virtual machine architecture that requires only about 1/10 of memory in comparison with conventional JavaVM. Furthermore, the size of distributed class files is reduced to about 40% of the original file size
