Abstract

본 논문은 AC-3와 MPEG-2를 모두 복호화할 수 있는 오디오 복호화기 구조를 제시한다. MPEG-2 합성필터는 AC-3와 공통점을 얻기 위해서 32 포인트 FFT를 활용하도록 변환되었다. 복호화기는 프로그래머블 오디오 DSP 코어와 공용의 합성필터로 구성되어 서로 다른 포멧을 효과적으로 분석, 복호화가 가능하다. This paper presents an audio decoder architecture which can decode AC-3 and MPEG-2 audio bit-streams efficiently. MPEG-2 synthesis filtering is modified by the 32-point FFT to share the common data path with the AC-3's. A programmable Audio DSP core and a hardwired common synthesis tilter are incorporated for effective decoding of two different formats.
