Aiming at the impact of radiation environment on integrated circuits in sensors

a new type of twodimensional（ 2D） error correcting code and its corresponding encoding and decoding circuits are designed. Firstly

the encoding algorithm of the 2D error correcting code is introduced

the information bits are divided into two equal rows arranged in a matrix form and parity bits are added to each row and column. Secondly

the decoding algorithm is designed

the encoding steps are repeated

the correct information bits are calculated using horizontal corrector and syndrome. Finally

using the interlacing arrangement method of information bits and parity bits

which makes it has stronger error correcting performance. Experimental results and performance analysis show that the designed novel 2D error correcting code has the advantages of strong error correcting performance

low power consumption

low time delay

etc. It is suitable for radiation hardened of integrated circuits of sensors in radiation environment.
