Abstract

See full text

The present application provides a three-mode storage method for program blocks based on check, comprising: first dividing the program to be injected into N blocks and checking each block to obtain the first checksum; then injecting the program to be injected and the first checksum twice in the program storage area, and the two injected programs are noted as the main program and the backup program, respectively; dividing the main program into N blocks, and checking each program block to obtain the second checksum during program run; dividing the backup program into N blocks and checking each block to obtain the third checksum; and comparing the checksum, second checksum and third checksum: if the three are consistent, performing no operation; updating the program or checksum and checking again, if the three are inconsistent.
