Partial reconfiguration (PR) enhances traditional FPGA-based systems-on-a-chip (SoCs) by providing benefits such as reduced area requirements and increased system flexibility. In multi-application PR SoCs, a dynamic resource manager (DRM) must efficiently orchestrate PR hardware resource management (access to and sharing of PR resources) in order to minimize the percentage of wasted/unused PR resources and reconfiguration time overhead. In this paper, we present DRM software that leverages two techniques, hardware module reuse and dynamic inter-module communication, to reduce wasted/unused PR hardware resources by 13% and reduce reconfiguration time by 33% as compared to a DRM without these techniques.
