摘要

本文介绍了一种基于DSP和RISC芯片的MPEG-4可视化简单配置文件和高级音频编码(AAC)解码器的实时嵌入式实现。我们利用无缝双缓冲存储器结构、用于半像素运动补偿(MC)的双MAC和AAC中的快速浮点到整数转换算法对MPEG-4模块进行优化。

Efficient real-time implementation of MPEG-4 audiovisual decoder using DSP and RISC chips

This paper presents a real-time embedded implementation of MPEG-4 visual simple profile and advanced audio coding (AAC) decoder using DSP and RISC chips. We optimize MPEG-4 modules using the seamless double buffering memory structure, the dual MAC applied for half pixel motion compensation (MC), and fast floating-to-integer conversion algorithm in AAC.
