Problems solved by technology

At the same time, this also brings a new problem. The control of a single small-scale FPGA is simple, while the control of multiple types of large-scale FPGAs is complex. How to efficiently control large-scale FPGAs to complete efficient configuration is the key

However, in response to this requirement, based on the above configuration modes, after searching relevant literature, there is currently no better method that can meet this requirement
