Method for loading on-site programmable gate array FPGA, apparatus and system

Abstract

The embodiment of the invention provides a method, a device and a system for loading a field programmable gate array. The method comprises: receiving a configuration file loading parameter of the field programmable gate array; selecting a configuration file from a plurality of configuration files according to the configuration file loading parameter; and loading the selected configuration file into the field programmable gate array. The method, the device and the system select corresponding configuration files according to different functions and load the configuration files into the FPGA by storing the plurality of the configuration files in advance, so as to realize normalization processing in the stages of manufacturing, stocking and so on and improve the efficiency of the stages.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for loading a field programmable gate array FPGA. Background technique [0002] The current mainstream FPGA (Field Programmable Gate Array) is volatile, that is, the content will be lost after power off, so it is necessary to fully consider how to load the FPGA when designing the system. One loading method is: after the single board is powered on, the configuration file is loaded to the FPGA through the CPU. The disadvantage of this method is that the system initialization takes a long time. Another loading method is: store the configuration file in the FLASH (flash memory) of the single board in advance, so that after power-on, the configuration file in the FLASH is loaded to the FPGA through CPLD (Complex Programmable Logical Device, complex programmable logic device) , to achieve automatic loading. [0003] The CPLD of the second loading method d...

Problems solved by technology

When there are multiple application scenarios that require the board to implement different functions, the existing technology can only perform different production, processing, stocking and after-sales services according to different application scenarios. This production method leads to low efficiency.
