Remote and partial reconfiguration of FPGAs: tools and trends

This work describes the implementation of digital reconfigurable systems (DRS) using commercial FPGA devices. This paper has three main goals. The first one is to present the trend of DRS, highlighting the problems and solutions of each DRS generation. The second goal is to present in detail the configuration architecture of a commercial FPGA family allowing DRS implementation. The last goal is to present a set of tools for remote and partial reconfiguration developed for this FPGA family. Even though the tools are targeted to a specific device, their building principles may easily be adapted to other FPGA families, if they have an internal architecture enabling partial reconfiguration. The main contribution of the paper is the tool-set proposed to manipulate cores using partial reconfiguration in existing FPGA.
