Error correction device, error correction method, and processor |
摘要 |
An error correction device includes: an error correction code generator that generates, from information unit data of data with a parity bit which includes m bytes of information unit data in which each byte has n bits of data and a total of m parity bits where 1 bit is provided for every 1 byte of the information unit data, a bit other than a bit corresponding to the parity bit out of bits constituting an error correction code used for correcting an error in the information unit data; an error detector that detects an error in the information unit data by generating an exclusive-OR of the data with a parity bit; and an error corrector that corrects an error in the information unit data by using a parity bit included in the data with a parity bit and the bit generated by the error correction code generator. |

1. An error correction device comprising:
an error correction code generator that generates, from information unit data of data with a parity bit which includes m bytes of information unit data in which each byte has n bits of data and a total of m parity bits where 1 bit is provided for every 1 byte of the information unit data, a bit other than a bit corresponding to the parity bit out of bits constituting an error correction code used for correcting an error in the information unit data; an error detector that detects an error in the information unit data by generating an exclusive-OR of the data with a parity bit; and an error corrector that corrects an error in the information unit data by using a parity bit included in the data with a parity bit and the bit generated by the error correction code generator when the error is detected in the information unit data by the error detector. |
