Linking High-Level Synthesis with FPGA Runtime Orchestration Tomkou, Despoina Ferikoglou, Aggelos Masouros, Dimosthenis Xydis, Sotirios Soudris, Dimitrios FPGA Orchestration Partial Reconfiguration FPGAaaS FPGAs are increasingly being adopted across the edge-to-cloud continuum due to their ability to provide both high performance and energy efficiency. However, the complexity of programming FPGAs often leads to deployed designs that underutilize available resources. FPGA multi-tenancy has been proposed to enhance resource utilization, yet monolithic designs and dynamic workload demands continue to challenge efficient FPGA usage and compliance with Quality of Service requirements. To address these issues, we propose a novel framework for the optimal orchestration of FPGAs across the edge-to-cloud continuum while meeting user demands. The framework generates approximations of Pareto-optimal designs for each application, capturing trade-offs between performance and resource usage with minimal bitstream generation. This information allows the runtime orchestrator to select the most suitable design based on available PR regions and the QoS requirements of each user. Experimental results demonstrate that the proposed approach achieves an average reduction of QoS violations by a factor of 8.1× across diverse workloads and baseline configurations. Overall, the framework offers a practical and effective solution for realizing FPGA-as-a-Service across the edge-to-cloud continuum.
