Binary conversion process of converting a program configured to operate in a specified device such that the program can operate in another device. However, as the binary conversion has a high dependence on an original device and a target device, new binary conversion needs to be performed in order to apply the binary conversion to a new device. This problem has been solved by applying an intermediate code used by a compiler as a method for solving the problem. As the method needs an additional conversion process, more time and resources are consumed when compared to an existing direct conversion method. Applying the method in an embedded environment or a real-time environment may be a problem. Thus, the present invention proposes a method for performing direct conversion like existing binary conversion, providing an abstraction model for instructions in order to reduce the dependency on the device, and automatically generate conversion rules on the basis of instructions represented with the abstraction model.
