    Abstract
  • A low-complexity MP3 decoder based on Broadcom embedded platform was proposed. C-code level optimization algorithms on inverse quantization, stereo decoding and alias reduction based on PC were proposed to further reduce the amount of memory usage and the computational complexity. Furthermore, the executable file of the optimized MP3 decoder was generated under the Linux environment, and transplanted to the set-top box based on Broadcom embedded platform. Experiment results showed that the total time for decoding was reduced on the embedded platform, and the goal of real time and fluent playing of audio files was fulfilled, which demonstrated the effectiveness of the proposed MP3 decoder. The proposed MP3 decoder could be applied in fields such as the set-top box based on Broadcom embedded platform and other portable devices.
