Research On Reconfigurable System Based On Novel FPGAs

Recently reconfigurable computing and software-hardware system co-design are two current issues, and their models are both based on reconfigurable system, meanwhile FPGA-based reconfigurable system is the pivotal concerning in the passing years. The key work in the thesis is related to novel FPGA-based dynamic reconfigurable system.In this thesis, our work includes three aspects. Firstly, we sponsor a novel FPGA architecture, which not only improves the logic intensity and resource usage in the device, but greatly reduce reconfigurable time and power dissipation. At the same time, communication issue is also handled. Secondly, we design a new set of development chain for reconfiguration, and address the concept about task status access (TSA) to order to solve many tough problems, such as preemptive hardware task scheduling, hardware resource defragment, and so on. It's beneficial for solving real time task immigration in software-hardware system in the future. Finally, with respect to software design on the reconfigurable system, we make a novel and high-efficient hardware scheduling algorithm based on first-fit self-adaptive algorithm. With this algorithm, the power consumption will decrease.To sum up, all three problems we target are relative to reconfigurable computing and software-hardware mixed system, which will be our emphasis in the next term.
