Abstract :
We present the software and hardware implementations of AMR codec for IMT-2000 system. The real-time implementations of AMR codec algorithm are achieved using TMS320C62xx DSP chip and Teak-Lite DSP core. We describe respectively efficient software schemes for coding AMR codec algorithm and hardware designs. The AMR codec is evaluated and confirmed in 3GPP test sequences, stand-alone test system and ETRI IMT-2000 prototype system
