Abstract :
Mobile networks and user equipments continuously evolve to circumvent the data traffic growth and the increasing number of users. However, the complexity and heterogeneity of such systems (3G, LTE, LTE-A, etc.) makes power one of the most critical metric. In this context, power estimation has become an unavoidable task in the design process. In this paper, a dynamic power estimation methodology for FPGA-based systems is presented. It aims at providing accurate and fast power estimations of an entire system prior to its implementation. It also aims at making design space exploration easier. We introduce an innovative scenario-level in order to facilitate the comparison of domain-specific systems. We show the effectiveness of our approach on several LTE baseband configurations which leads to a low absolute error, compared to classic estimations. It also exhibits a high speed-up factor which is determinant during design space exploration.
