| Abstract: | To meet the need of special application of switching the FPGA configuration bit stream to achieve different functions,researchers design an FPGA multi-configuration system using mass Flash memory as bit stream carrier.It has a higher speed in the programming of configuration bit stream due to the use of JTAG interface and less time for the FPGA configuration through slave SelectMap mode.Meanwhile,it achieves the in-system configuration bit switch through the serial communication.The practical application sh... |
