This paper deals with the design of 2-D multiplierless FIR digital filters. First, a special class of multiplierless 1-D FIR filters is designed with coefficients which are a sum or difference of power of two. This is then mapped into 2-D multiplierless FIR filters by the McClellan transform. This technique has the advantage that it is very fast, because only a 1-D filter must be designed. Also, the hardware implementation for these 2-D FIR filters is very attractive and efficient.
