HARDWARE IMPLEMENTATION OF THE PCM CODEC FOR VOIP TELEPHONY

摘要

This paper presents the hardware implementation of the pulse code modulation coder and decoder (PCM Codec), that aims at improving the delay of the speech compression of this codec, which is originally implemented in software for Voice-over Internet Protocol (VoIP) Telephony. This design provides a solution known as intellectual property (IP) core ready to be deployed in a reconfigurable architecture with other voice codecs. Such architecture can then be used to improve the Quality-of-Service (QoS) of VoIP Telephony.
