Embodiment Construction

[0030] A kind of FPGA dynamic function switching method of embedded device, comprises the following steps:

[0031] Step 1) form the target file mapping table according to the one-to-one correspondence between device functions and FPGA target files;

[0032] Step 2) analyzing the configuration file information and the instruction information to obtain the information of the function to be switched;

[0033] Step 3) According to the information of the function to be switched, the corresponding target file is searched in combination with the above-mentioned target file mapping table;

[0034] Step 4) Load the found target file.

[0035] This method can avoid the cumbersome and error-prone disadvantages of manual device management, and can enhance the efficiency and convenience of device management. Specifically, such as figure 1 , figure 2 with image 3 As shown, the specific steps of the method are as follows:

[0036] 1 Collect the FPGA target files corresponding to dif...

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.

Description
