Two ways to reconfigure FPGA chips

FPGA's dynamic reconfiguration technology can be divided into two types according to the different structures inside the FPGA chip, namely dynamic global reconfiguration and dynamic local reconfiguration. Dynamic global reconfiguration means that the host computer loads a new configuration file to the FPGA chip, and this configuration file contains all the resources in the entire FPGA that are involved in the new task requirements, thereby realizing FPGA reconfiguration. Dynamic local reconfiguration only needs to generate a configuration file for the different partial logical functions between the two functional requirements, and load it into the specified reconfigurable area in the FPGA for reconfiguration.
