Open cores based system on chip platform for telecommunication applications: VoIP

In this paper, we present a platform for system on chip (SoC) implementation that is suitable for telecommunication applications. To build the platform, we have adopted the OpenCores-Openhardware design concept. The benefit of using the OpenCores methodology is flexibility, reuse and accessibility of the cores at free cost. We demonstrate how the open hardware trend can help designers to build complex integrated circuits such as SoCs at low cost. To test the platform, our first application is a SoC implementation of a Voice Over IP (VoIP) Gateway. The first preliminary results show that the whole SoC can be implemented in the field programmable gate array (FPGA) - XC2V1000 circuit.
