Mda Approach in Embedded Systems with Strict Real-time Response and On-the-fly Modelling Requirements

The paper presents a proposal of a method for MDA based “on-the-fly” modelling of Musical Real Time Applications. The method is based on use of the Executable and Translatable UML approach (xtUML) with regards to implementation on embedded systems. Since the goal is to implement a real-time application requiring certain real-time Quality of Service (QoS) properties, the real-time response requirement influence on modelling is discussed as well. To provide a solution for the main user requirement, which is a possibility for an application model modification in real-time (during execution), we discuss a method, which splits the application into two parts. The first part is the implementation environment – the programmer/provider system, which will provide for the runtime environment of the second part, the user model itself, modelled using xtUML on-the-fly. The advantage of such separation results in an increased modelling easiness and reasonable real-time performance on user modelling as well as low signal
