Erdogan The aim ofthis paper is to present an adaptable Fat Tree NoC architecture for Field Programmable Gate Array FPGA designed for image analysis applications. Traditional Network on Chip NoC is not optimal for dataflow applications with large amount of data. On the opposite point-to-point communications are designed from the algorithm requirements but they are expensives in terms of resource and wire. We propose a dedicated communication architecture for image analysis algorithms. This communication mechanism is a generic NoC infrastructure dedicated to dataflow image processing applications mixing circuit-switching and packet-switching communications. The complete architecture integrates two dedicated communication architectures and reusable IP blocks. Communications are based on the NoC concept to support the high bandwidth required for a large number and type of data. For data communication inside the architecture an efficient time-division multiplexed TDM architecture is proposed. This NoC uses a Fat Tree FT topology with Virtual Channels VCs and flit packet-switching with fixed routes. Two versions of the NoC are .
