Abstract

The invention discloses a data storage error-proofing processing system. The data storage error-proofing processing system comprises client data DATA, an MCU processor connected with the client data DATA, and a FLASH memory connected with the MCU processor, wherein the client data DATA comprises DATA1, DATA2, DATA3,..., DATAn. The MCU processor comprises a default data unit, a data processing unitand a FLASH memory, and is provided with a plurality of blocks (BLOCK). The data processing unit comprises a data reading module, a data negation module and a checksum module, and further comprises acombined data structure module, an exclusive OR value module and a data judgment module; and the data judgment module and a default data module which are connected with client data DATA, the combineddata structure module is connected with a FLASH memory, and the FLASH memory is connected with a data reading module. The invention provides the data storage error-proofing processing system and method capable of replacing an EEPROM memory with a FLASH memory.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia, in particular to a data storage error prevention processing system and method. Background technique [0002] In car audio products, customer data and product configuration data need to be stored. At present, the commonly used solution is to use EEPROM memory. EEPROM memory can save data when power is off, and supports more than 1 million write times. Existing FLASH memory is generally used to store running programs, does not need to be erased and written many times, and the number of erases and writes is more than 100,000 times, which cannot meet the requirements of data storage. The invention proposes a data storage error prevention processing system and method which can use FLASH memory instead of EEPROM memory. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing FLASH memory, which is generally used to store running pr...
