Abstract

Provided is a Java bytecode translating method which includes: a bytecode fetch step (S1 10) that fetches a Java bytecode from a Java class file; a static field address detection and data processing step (S140) which gains access to a field (130) according to a first field address (FA1) and processes data; a static field address storage step (S 150) that stores a first upper field address (FAU1) including upper bits among bits of the first field address (FA1) in a first storage portion (110), and which stores a first lower field address (FAD1) including remainder lower bits excluding the first upper field address (FAU1) among the bits of the first field address (FA1) in an operand field (120b); a static operation code translating step (S 160) that translates an operation code stored in an operation code field (120a) into a new static field accessing operation code (NOPA); a first field address creation step (S240) that creates a second field address (FA2); and a first data processing step (S250) that gains access to the field (130) according to a second field address (F A2) and processes data.
