A packet processor can use Dynamic Function eXchange to change its processing functions quickly, based on the packet types received. In the following figure, a packet has a header that contains the partial BIT file, or a special packet contains the partial BIT file. After the partial BIT file is processed, it is used to reconfigure a co-processor in the FPGA. This is an example of the FPGA reconfiguring itself based on the data packet received instead of relying on a predefined library of partial BIT files.
