FPGA (Field Programmable Gate Array) based power failure protection system and method

Abstract

The invention relates to an FPGA (Field Programmable Gate Array) based power failure protection system and an FPGA based power failure protection method. The system comprises a power failure detection module, a power supply module, a CPU (Central Processing Unit) minimum system, an FPGA processing module and a reset control module, wherein the power supply module is used for supplying power to other four parts respectively, the power failure detection module is used for detecting whether to power failure occurs and outputting a monitoring signal; the FPGA processing module is connected with the power failure detection module for detecting the monitoring signal output by the power failure detection module; the CPU minimum system is connected with the FPGA processing module for receiving a power failure warning signal from the FPGA processing module and outputting a reset control signal; the reset control module is connected with the CPU minimum system for resetting. The system overcomes the disadvantages that the used standby battery has large volume, high cost, short life, poor reliability and the like, and utilizes the own resources to provide a method for timely backing up and protecting system data and programs under a condition that the system is powered down suddenly, and the system has the advantages of small volume, low cost, easiness in realization, high reliability and the like.

Description

technical field [0001] The invention relates to the technical field of communication electronics, in particular to an FPGA-based power-down protection system and method. Background technique [0002] With the development of communication and electronic technology, higher and higher requirements are put forward for the reliability of equipment. In various emergencies, equipment can protect the system, and then normal startup and operation become one of the indispensable standards for measuring reliability. one. In the process of sudden power failure of the equipment, because each part of the system is in an uncontrollable level state, program files and data may be destroyed, affecting the normal operation of the system. Therefore, in equipment with high reliability requirements, a power-down protection circuit must be provided. [0003] At present, there are several power-failure protection methods: one can provide backup power for the device to ensure that the backup power...
