Implementation of MP3 Playout System on ARM-based SoC Development Platform

MP3 compression format is essential categorized one of the MPEG (Moving Picture Experts Group) standards for digital audio compression nowadays. For its superiority and convenient,MP3 has been widely used in multimedia player and storage application. In this thesis, we use software/hardware co-design methodology to design the MP3 player system. In addition, system level scheduling is adopted to arrange the execute time of SW and HW and significantly reduce the hardware cost under the construct of real-time processing. We can obtain fewer extra hardware cost while attaining the goal of real- time playing system. In order to perform software/hardware partitioning, simulate and analyze the MP3 application program to find out the critical parts with high time complexity and regular computation. These parts with high time complexity, e.g. IMDCT and Poly Phase synthesis filter bank, then are implemented by hardware to achieve better system performance. We use high level synthesis concept to optimize the hardware part and integrate software and hardware¡Asuch that communication between software and hardware can be performed smoothly. Finally, MP3 player system is using verified by hardware¡Bsoftware co- verified methodology on an SoC development platform.
In order to build a complete verification environment, we attach extra input and output interfaces to the SoC development platform, e.g. the network card and sound card. Write some driver to drive related peripheral device. Since OS is conducive to the operations between software and hardware, Linux OS is ported to the SoC platform to manage software and hardware resources and drive the peripheral devices.
