Tomorrow’s pocket devices will all have Internet-based communication capabilities. The advent of mobile phones, PDAs (Pocket Data Assistant) and pocketPC’s joint to the newcomer’s third generation wireless networks such as UMTS will soon allow everyone to be connected, everywhere. In this competitive marketplace where many similar products compete for the consumer attention, performances level is a very important criterion.Videoconferencing, digital music broadcast, speech recognition are a few example of the new features allowed by the new third generation networks. This kind of multimedia, data oriented content requires highly efficient architectures; and nowadays mobile system-on-chip solution will no longer be able to deal with the critical constraints like area, power, and data computing efficiency. In this paper we will propose a new dynamically reconfigurable network, dedicated to data oriented applications such as the one targeted on third generation networks. Principles, realisations and comparative results will be exposed for some classical applications, targeted on different architectures.
