| Abstract: | A multimedia application SOC chip is introduced in this paper, and the MP3 design based on ATJ2135 is presented. With the embedded CPU and μC/OS-Ⅱ RTOS, the embedded operation system was realized and the applications, user data processing are accomplished. With the embedded DSP and audio decoding method, the MP3 files decoding was implemented. This paper introduces also the software and hardware design, the decoding procedure of MP3, RTOS design and the process of system testing based on ATJ2135. |
