    • PURPOSE: An additional code generating apparatus for a VM(Virtual Machine) and a method thereof are provided to increase a area able to accelerate through a JITC(Just In Time Compiler) and improve performance of the VM by increasing generation of a machine code. CONSTITUTION: An information collecting unit(201) collects trace information indicating logic flow which a byte code is performed. If the byte code is not compiled, a code decision unit(202) decides a byte code section to compile into a machine code by using the trace information. A compiler compiles the byte code section into the machine code. The compiler and an interpreter performing the byte code are operated on separate cores. The information collecting unit searches for a route of the byte code performed on the interpreter and collects trace information.
