Modeling and Exploration of a Reconfigurable Architecture for Digital Holographic Imaging

Abstract — The use of coarse-grain reconfigurable architectures (CGRA) is a suitable alternative for hardware acceleration in many application areas, including digital holographic imaging. In this paper, we propose a CGRA-based system with an array of processing and memory cells, which communicate using a local and a global communication network, and a stream memory controller to manage data transfers to external memory. We present our SystemC-based exploration en-vironment (SCENIC) and methodology used to construct and evaluate systems containing reconfigurable architectures. A case study illustrates the advantages with rapid system level exploration to find and solve bottlenecks in complex designs prior to RTL description. I
