Abstract: Error correction codes (ECC) are effective means to deal with single-bit or double-bit errors in data. However, an overly complex encoding method will reduce read and write performance. To solve this problem, a dynamic error correction mechanism based on the extended Hamming code is proposed. The parity bit included in the extended Hamming code is used to optimize the error detection module, and it can perform extended Hamming code and parity check dynamically. The hardware description language Verilog is used to realize the mechanism, and the simulation is carried out. The analysis results show that using this mechanism can effectively reduce dynamic power consumption compared with using extended Hamming code verification.
