Abstract: This paper describes design, implementation, verification and optimization of a power line modem with model-based evaluation approach. Nowadays, model-based design for embedded systems is used extensively to accelerate the development time and to improve the quality of the resulting applications by systematic design and test. The majority of DSP designers today use the Math Works software includes MATLAB and/or Simulink as a foundation tool not only for simulation but also for real-time target specific C-code generation. In our modem project, all parts including transmitter, receiver, I/O drivers and startup protocols have been realized entirely in Simulink environment for simulation and hardware implementation. A floating-point DSP has been carried out to minimize the time required to convert simulation software into real-time code. In order to verify the algorithms, real-time data exchange has been developed to test our DSP designs in-situ with real data. Finally, for code optimization, profiling method has been employed to identify segments of generated code that may benefit from additional modification.
