Processing method and device of chip configuration information

Abstract

The invention relates to the technical field of internets, in particular to a processing method and device of chip configuration information. The method and device aim at solving the problem that reading of existing chip configuration information is easily influenced by abnormal environment interference or malicious destruction, which influences the work of a chip in turn. The method comprises the steps that each group of configuration information which is saved in advance is read in a first designated memory area, aiming at one or more groups of read configuration information, a corresponding proof test value is calculated, and whether the calculated proof test value is in accordance with a reference proof test value which is saved in a second designated memory area or not is judged; if not, an output result is determined based on each preset processing mode of each group of configuration information; accordingly, after the chip is powered on, even if the read configuration information is influenced, corresponding processing can be conducted based on the preset processing mode corresponding to each group of configuration information, so that a final output result cannot influence the normal work of the chip, the stability and the safety of a chip system are improved, the logical structure is simple, the occupied resources are few, and the method is wide in application range.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a chip configuration information processing method and device. Background technique [0002] The configuration information of the chip is often used to distinguish the direction of the chip, the characteristics of the chip, etc., so that the chip can be applied to different application scenarios. Generally speaking, the configuration information will be stored in the non-volatile memory (Non-Volatile Memory, NVM) of the chip. When the chip is powered on, the system will automatically read the relevant configuration information from the NVM. [0003] However, as NVM is used as a storage logic unit, factors such as power supply voltage, operating temperature, and data retention time may affect the stability of reading configuration information from NVM. For example, if the power supply voltage does not reach the set minimum operating voltage, the It may be due to insufficient...
