Using UML as a front-end for an efficient Simulink- based multithread code generation targeting MPSoCs

UML provides all benefits from the object-oriented paradigm, such as encapsulation and reusability, while Simulink is targeted to support multiple models of computation such as stream processing and control. Recently, a Simulink-based design flow was proposed to address MPSoC systems, generating multithread code. However, MPSoC modeling with Simulink is error-prone and does not adequately cope with MPSoC modeling. In addition, software engineers usually prefer to employ UML, due to its higher abstraction level. This work proposes the mapping of system models from UML to Simulink, thus enabling a Simulink-based MPSoC design flow. In this way, the same UML model can be used as a front-end for both a traditional software design flow, relying on the usage of several tools that are already available to handle the complexity of this kind of design starting from UML, and a Simulink-based one.
