| Abstract: | This paper uses a repetitive algorithm for determining the corrupted bit position,implement an efficient hardware CRC check circuit which can detect multiple bits error and correct single-bit transport error in 32-bits of original data or in 8-bits of CRC code.The experiment result shows that the check circuit has low complexity and high processing speed relative to look-up table. |
