System and method for reducing execution time of bytecode in a java virtual machine

摘要

A system and method for reducing the bytecode execution time in the Java virtual machine are disclosed. The system includes a DB cache (140) to store old machine code converted from a bytecode, a machine code change unit (150) to change the old machine code to new machine code by removing a predetermined instruction included therein, a register management unit (170) to manage stack data necessary for operations of the new machine code and a register file to provide a register region to conduct the operations, and a machine code information storage unit (160) to store basic block information on the new machine code and spill and fill execution information in the stack of the register file.
