VLSI implementation of an MPEG-4 audio decoder is described, which is dedicated to portable audio appliances. MPEG-4 audio surpasses conventional audio codec schemes in terms of sound quality and compression rate. Based on the results of sound quality evaluation, a low-power architecture is devised by means of frame-level pipeline and optimization of functional datapath. The proposed MPEG-4 audio decoder has been implemented with the use of 0.25 μm CMOS library, which integrates 30 k gates and dissipates 4.54 mW at 2.5 V supply
