- An Opcode Level Energy Consumption Model for a Java Virtual Machine
- This paper establishes a general framework for estimating the energy consumption of an embedded Java Virtual Machine JVM. The paper has designed a number of experiments to find the constant overhead of the Virtual Machine and establish an energy consumption cost for individual Java Opcodes. The results show that there...
