MPEG-2／4AAC音频编码模块的验证

先进音频编码（AdvancedAudioCoding，AAC）以其多声道、多采样率、高压缩比、音质好等特点被广泛使用。文中首先介绍了MPEG-2／4AAC音频编码技术；接着基于MPEG-2／4AAC音频编码原理，开发了时钟复位、寄存器配置和音频数据收发的BFM模型，搭建了音频编码模块的RTL级虚拟验证平台，同时归纳了验证项；最后基于此验证平台和验证项，对设计进行了全面的仿真验证。实践证明该验证方法效率高、收敛快、覆盖率高，取得了较好的效果，为后续的FPGA平台验证和芯片应用提供了有力的保证。

Verification of MPEG-2/4 AAC Audio Encoder Module

AAC （ Advanced Audio Coding） is outstanding in the digital audio compression field with better audio quality, higher compres- sion rates,more channels and variety of sampling rates. It first introduced the MPEG-2/4 AAC technology, and then constructed RTL level verification platform of audio encoder module, setting up several bus function models according to difference functions based on the principle of MPEG-2/4 AAC. The simulation of audio encoder module has also been achieved at last. The method of the simulation that has been implemented during the whole simulation procedure improves verification efficiency and speod,provides credible guarantee for FPGA platform verification and speeds up the time to market.
