A new approach is proposed to translate existing software programs from one in-

struction set other instruction sets at the assembly level. The behaviors of instructions are

abstractly represented as manipulation of the machine state. The behavior of each basic

block of the software program is then represented as state transition pair. Instruction set

retargeting is then modeled as the problem of finding sequences of instructions accom-

plishing the same machine state transitions at the target machine as does the software

program at the source machine. The proposed approach has been successfully demon-

strated for software translation between several industrial microcontrollers.
