英文摘要：

Word level representation of multi-output Boolean function and its mixed-polarity Reed-Muller （MPRM） using coefficient matrix is proposed for polarity conversion of multi-output MPRM circuits. Based on this representation, a polarity conversion algorithm is presented. Experimental results show that, in comparison with bit level representation, the proposed word level representation based polarity conversion algorithm can significantly reduce the time consumed for polarity conversion of multi-output MPRM circuits.
