Embedded systems can be viewed as scaled-down versions of their stand-alone counterparts. In many cases, the software abstractions and libraries for embedded systems can be derived from libraries for stand-alone systems. One such example is the Java library for Java Virtual Machines. An embedded system does not always support all features as in the case of an embedded JVM that does not support floating-point operations. In such cases, an existing library needs to be migrated to the embedded platform. Libraries are large collections of code and manual migration is a daunting task. In this paper, we provide an automated approach to the library migration problem using program transformations. The solution developed in this paper enables rapid adaptation and re-targeting of Java libraries in the presence of evolving libraries and evolving embedded platforms.
