Abstract :
This paper proposes optimization techniques to implement MPEG audio decoding algorithms in real-time using a general-purpose 32-bit MCU RISC processor. We implemented an MP3/AAC decoder using an ARM-based RISC MPU and its test board. Both the designed decoders with the proposed optimizations could achieve decoding processes in real-time within an operating frequency of 35 MHz.
