Methods for embedding codes executable in a first system having a first microprocessor into codes executable in a second system having a second microprocessor are described herein. In one aspect of the invention, an exemplary method includes providing first codes having a routine, the first codes being compilable to be executed in the first system, and compiling the first codes, resulting in second codes; the second codes comprising opcodes of the routine executable by the first system, which convert the second codes into third codes automatically, the third codes being compilable to be executed by the second system; this is followed by compiling the third codes, resulting in the fourth codes being executable in the second system, and linking the fourth codes, generating an executable image and executing the executable image in the second system. Other methods and apparatuses are also described.
