HE-AAC V1 Decoder Design Based on SW/HW Co-design
Peilin Liu · Audio Engineering · 2008
A design and implementation for HE-AAC(High Efficiency Advanced Audio Coding) V1 decoder, which is based on the methodology of SW/HW Co-design, is presented. The parallelism between SW HW, and the design of HW engine for QMF are introduced. Real-time decoding for 2-channel music with the sample rate of 44.1 kHz and bit rate of 48 Kb/s can be obtained at about 45 MHz according to the simulation.
