As Digital Signal Processors and digital signal processing technology are in increasing process, optimization of previously developed code for Digital Signal Processors has become more and more important. This paper presents an approach for porting Dolby Pro Logic II audio decoder, from the reference platform to the targeted DSP architecture. The overall system is firstly analyzed and then ported to the DSP platform. The system features are validated and verified using software simulations and audio system measurements in real-time conditions. The application of targeted DSP system is in audio processing for digital TV receivers, mobile phones, headsets, etc. The results have shown that execution time is decreased in the final system, and that higher sampling rates are enabled for better performances.
