VoIP DSP Functionality in Software on Linux Based Power Pc Platform

Hemant Agrawal

Abstract—These network devices in small and medium business and home market are incomplete without supporting voice over IP. Traditionally dedicated DSP based solutions are used for processing the packetized voice with Quality of Service support. However it is not cost-effective for the low-end devices to have a DSP on board. One of the challenges in providing a VoIP solution is extracting the same level of performance from a Linux based PowerPC that a DSP would offer. This paper covers the challenges in implementing VoIP framework on Linux. This results in a “software-DSP” implementation on Freescale’s Power PC platforms.

Index Terms—VoIP, DSP, PowerPC, speech coding, real time patch.
