Abstract: An optimized reconfiguration algorithm based on dynamic voltage and frequency scaling (DVFS) is provided, which mainly has the following contributions. The optimized reconfiguration algorithm based on DVFS proposes a DVFS-based reconfiguration method, which schedules user tasks according to a degree of parallelism (DOP) of the user tasks so as to reconfigure more parallel user tasks, thereby achieving higher reliability. The optimized reconfiguration algorithm based on DVFS proposes a K-means-based heuristic approximation algorithm, which minimizes the delay of the DVFS-based reconfiguration scheduling algorithm. The optimized reconfiguration algorithm based on DVFS proposes a K-means-based method, which reduces memory overhead caused by DVFS-based reconfiguration scheduling. The optimized reconfiguration algorithm based on DVFS improves the reliability of a field programmable gate array (FPGA) system and minimizes the area overhead of a hardware circuit.

Abstract: A window-based dynamic scrubbing scheduling method is provided. By dynamically scheduling a user task and a scrubbing task, the method can reduce scrubbing conflicts of a field-programmable gate array (FPGA) scrubbing module and scrub each user task in a timely manner as much as possible. The method greatly reduces area and energy consumption overheads of a hardware circuit, and improves system reliability. The method proposes a negotiation-driven scrubbing scheduling algorithm and an integer linear programming (ILP)-based optimization-driven scrubbing scheduling algorithm. Based on global conflict information, the algorithms in the method can scrub more user tasks and improve the system reliability. The method ensures reliability of a mixed-criticality task set system. The method provides a dynamic voltage and frequency scaling (DVFS)-based multi-Internet Content Adaptation Protocol (ICAP) port allocation algorithm that can explore an impact of FPGA architecture support on the system reliability to further optimize the system reliability.
