Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] See figure 1 , Is a schematic diagram of the erasure correction device of the present invention. The device includes two parts: an encoding module and a decoding module. The encoding module processes 16 input data blocks to obtain two check data blocks. The decoding module uses the received two check data blocks to erase some of the received missing data. .
[0028] See figure 2 , Is a schematic diagram of the specific encoding process of the present invention.
[0029] The function of the coding part is to generate 2 check blocks (output) from no more than M=16 pieces of original data (input). In flash memory, each data block is 16KB, although other sizes are also possible.
[0030] Among them, the first data block is obtained by XORing the corresponding byte positions of the 16 original data blocks.
[0031] If the number of original data blocks is less th...
