In this paper a method for decomposition of encoding and symbolic functional decomposition for functions functions with multi-valued inputs is presented. Decomposition is with multi-valued inputs. The goal of our method is to find performed simultaneously with encoding of symbolic values. In encoding that simplifies functional decomposition. Input this way an impact of input encoding on decomposition efficiency encoding is built in balanced decomposing strategy based on is taken into consideration during optimization. The goal of our . and serial decompositions[2]. E method is to find encoding that maximally simplifies functional paaled serial decompsitioi E mnt al rests decomposition. Experimental results showed that the presented showed that our method significantly reduces the cost of method significantly reduces the cost of FPGA implementations FPGA implementations for most evaluated benchmarks. for most evaluated benchmarks.Next section presents a basic theory concerning functional decomposition and blanked algebra which is the mathematical
