GARCIA MONTOYA, Mario; LEON GONZALEZ, Nelia R.; MARIN CONTRERAS, Víctor  and  YANEZ DE LA RIVERA, René. Implementation of VoIP Communication Protocols over Altera's FPGAs. EAC [online]. 2014, vol.35, n.3, pp.39-47. ISSN 1815-5928.

An RTP/RTCP protocol design and implementation solution over programmable logic devices is proposed; those protocols are needed for Voice over IP technology start up. The design is based on C++ language and it employs the Altera tools such as: Nios II IDE, Quartus and SOPC Builder. Nios II embedded processor is used in an FPGA, with the real time operative system MicroC/OS-II. The proposal tuning-up is implemented over the «Nios II Development Kit», which results are checked with the Nios II IDE console and with the Kit peripherals. Finally, the communication between two conventional PCs running the application over Windows XP is tested.

Keywords : RTP; RTCP; Nios II; MicroC/OS-II; FPGA; C++.
