Abstract: FPGA provides a powerful programmable interface that supports flexible field-programmable capabilities. Dynamic reconfigurable design methods can optimize traditional FPGA applications in terms of size, weight, power, and cost. The dynamic reconfigurable implementation system, which is composed of control, storage and interface, can realize dynamic reconfiguration of FPGA, but it needs to add more devices，make FPGA application system become more complicated. Based on the current dynamic reconfigurable principle, this paper proposes the principle and implementation method of dynamic self-reconfiguration system.This method can modify the self-reconfigurable partition by adding self-reconfiguration module to the static logic, so as to realize the dynamic self-reconfiguration of itself. This paper designs two kinds of LED lights flashing mode module, the experimental results show that: through self-reconstruction technology, you can achieve these two flash mode switching. And proves the feasibility of self-reconfiguration technology.
