摘要
本文给出了MPEG-4AAC-LD解码器在定点DSP芯片TM1300上的一种实现方案。介绍了AAC-LD解码算法原理和TM1300芯片,讨论了对AAC-LD解码器关键模块的优化,并描述了基于TM1300芯片特性的优化设计。
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.
