Low-power-dissipation FPGA self-adaption loading method and system

Abstract

The invention provides a low-power-dissipation FPGA self-adaption loading method and system. The low-power-dissipation FPGA self-adaption loading method and system are used for solving the technical problems existing in an existing loading method that an FPGA is high in power dissipation and a large number of internal resources are consumed. An external processing module packs multiple configuration files with different functions to obtain a total configuration file, and the total configuration file is written into a configuration information storage module; a target FPGA automatically loads a first configuration file from the configuration information storage module to achieve initial configuration; an FPGA function detection module detects the matching features of external input data and a current configuration file, and if the external input data is matched with the current configuration file, the target FPGA enters a normal work mode; if the external input data is not matched with the current configuration file, a self-adaption re-loading process is triggered, the next configuration file is loaded, and after the configuration is completed, the detection step is repeated. The low-power-dissipation FPGA self-adaption loading method and system can effectively lower the power dissipation of the FPGA and the consumption of the internal source of the FPGA.
