FLASH ERROR CORRECTION

摘要

A data processing device for applying an error correction algorithm to data written to and data read from a re-writable memory, the data processing device comprising a coding unit implemented in hardware, the coding unit being capable of performing a coding operation in which it receives a first set of data to be written to the memory, processes that data in accordance with the error correction algorithm to form a second set of data and outputs the second set of data for writing to the memory, and an error detection operation in which it receives data read from the memory and processes that data in accordance with the error correction algorithm to determine whether the read data contains an error and an error correction unit implemented in software, the error correction unit being arranged to receive read data that contains an error, process that data in accordance with the error correction algorithm to correct said error and thereby form corrected data, and output the corrected data.
