The MP3 player uses the digital signal processor DSP (Digital Sign Processer) to complete the task of processing transmission and decoding of MP3 files. DSP rules the data transmission of the Walkman, device interface control, file decoding playback and other activities. DSP can perform a variety of processing tasks in a very short time, and this process consumes very little energy (this is also a significant feature of its suitability for portable players).
