| Abstract: | A fast dynamic loading method to FPGA based on CPLD and FLASH is designed. In this paper, design project, system connection map and typical application are presented, and the loading flow and timing design are introduced in detail. Compared with other loading methods, this means has more memory and flexibility. It＇s convenient for FPGA to update and configure dynamically online. A good application foreground in Software Radio based on FPGA can be achieved by this means. |
| Keywords: | FPGA dynamic loading SDR. online update |
