Automatic Code Generation in Model Based Design and Digital Signal Processing

As modern industrial systems and applications become more sophisticated, the need for automated, user-friendly and fully integrated high-performance development environments becomes critical. In this context, the model based design (MBD) of dynamical systems is becoming increasingly popular, with engineering tools such as Matlab, Simulink, Metalau team SciCos, Wolfram SystemModeler finding widespread applications. These tools offer modelling, simulation, verification, and in some cases, automatic code creation capabilities for desktop software, embedded systems and robotics. However, all models need be transformed into trustworthy machine instructions for implementation on actual hardware. Tools like Matlab and Simulink offer coder solutions, which auto generate codes as a part of the overall model based design methodology. In model based design, the hierarchical control architecture model may be quickly and accurately transformed into code and implemented on hardware. Manual code conversion from system models is no longer a viable option due to the complexity of modern systems. This paper presents a brief review of some of the recent studies investigating automatic code generation in digital signal processing and model based design paradigms.
