Abstract

With the development of digital signal processing technology and DSP (Digital Signal Processor), MP3 format music (ISO/IEC 11172) is popular which is using MPEG-1 international audio standard. But most of the mp3 decoder depends on unique application specific integrated circuit, so it is lack of flexibility and upgrade. To meet this requirement, a fixed-point DSP Based MP3 Decode System is designed which can accomplish analysis and processing of MP3 audio digital signals as well as sampling and transmitting external analog audio signals through CODEC. It also includes Flash and hard disk to store programs and data, 128K-Byte RAM as data buffer, and USB controller to realize communication between system and PC. Its effectiveness is verified by experiments.
