Multiplierless realization of linear DSP transforms by using common two-term expressions

Recently, most DSP systems have used multirate signal processing techniques or transforms for reducing computational complexity without compromising t he system quality. In these techniques, realizing each constant separately is a redundant process as some constants appear more than once, and increas es area and power consumption of the system. This paper introduces the conc ept of handling all coefficients in the system at the same time. To do this , the two-term expressions of constants in a system for adder and shifter m inimization is presented.
