Error control codes are effective to improve the reliability and precision of the vector-matrix multiplications executed on unreliable low-precision hardware. Since numerical errors of small magnitude may not affect the reliability or performance of system significantly in some applications, such as neural networks and image processings, this report presents error control codes which can efficiently correct large magnitude errors while allowing small magnitude errors. The proposed coding modifies the systematic encoding of nonbinary polar code, that is, we improve the code rate by diverting some check symbols to information symbols, while allowing small magnitude errors in the information symbols. Simulation results show that the proposed coding has higher random error correction capability compared to existing method. |
