Abstract :
The MAGALI chip is a 65nm digital baseband dedicated to advanced telecommunication applications. Based on a 15-router mesh Network-on-Chip - NoC, it embeds 22 Processing Elements - PE performing the different functions of a complex baseband in a programmable manner. The NoC framework is based on asynchronous routers which provide a complete Globally Asynchronous Locally Synchronous - GALS framework. Thanks to this structure, each PE is a synchronous island with a programmable frequency. On the architectural side, the NoC supports fast reconfiguration thanks to a distributed scheme. In this demonstration, we propose to show the reconfiguration capabilities of the MAGALI chip on three modes of a 3GPP-LTE receiver part, by switching on-the-fly between these three modes. The resulting transmission quality with different levels of upcoming signal noises is shown.
