| Abstract: | This paper presents the solution of MPEG-4 Low-Delay Audio Decoder on the fixed-point DSP chip TM1300. Firstly, a brief introduction to the fundamental principle of AAC-LD decoding algorithms is presented. Subsequently, some main features about TM1300 and techniques to optimize the decoder's key modules as well as several optimization ways with the particular features of TM1300 are discussed. |
