Automatic code generation from UML for data memory optimization in microcontrollers

Design of applications for microcontrollers is typically constrained by the limited hardware capabilities of this devices. As embedded systems, the specificities of each application should be analyzed to overcome these limitations, but this is not easy to do. To help in this process, this paper proposes an analysis of some communication semantics, its potential impact on data memory usage and alternatives to minimize it. Moreover, a design tool capable of automatically generate code for microcontrollers from UML models is proposed. That way, engineers can automatically generate implementations from the communication semantics specified in the UML model. That way, exploration of the design alternatives can be done with minimal recoding effort.
