Low power implementation of MDCT/IMDCT for MP3 audio decoder
The MDCT/IMDCT is the basic processing component for digital audio compression. It is also the most computationally intensive operation in audio compression standards. MP3 is still used in the audio standards for audio compression. This paper presents a new and efficient implementation of 12/36-point MDCT/IMDCT architectures for MP3. The proposed architecture utilize Chartered 90nm CMOS technology and optimized for low power applications. Low power libraries and clock gating technique are used for power reduction. Our experimental results show the effectiveness to implementation of MDCT /IMDCT core for MP3
