Abstract

The invention discloses an FPGA (Field Programmable Gate Array) dynamic function switching method and device for embedded equipment. According to the invention, firstly, a target file mapping table is formed according to a corresponding relationship between equipment functions and FPGA target files; then configuration file information and instruction information are analyzed to obtain information of a function to be switched, and according to the information of the function to be switched, the corresponding target file is searched by combining the target file mapping table; finally, the searched target file is loaded. By the process, the FPGA dynamic function switching method and device solve the problems of tediousness and easiness for generating a fault when different FPGA programs need to be downloaded for different devices, and are more efficient, convenient and rapid in management when different FPGA programs are used for different devices; moreover, a very convenient method is provided for full functional testing of the devices.
