EasyPR — An easy usable open-source PR system

In this paper, we present an open source partial reconfiguration (PR) system which is designed for portability and usability serving as a reference for engineers and students interested in using the advanced reconfiguration capabilities available in Xilinx FPGAs. This includes design aspects such as floorplanning and interfacing PR modules as well as fast reconfiguration and online management. The system features relocatable modules which can even contain reconfigurable modules themselves, hence, implementing hierarchical PR.
