Abstract
The vertical common subexpression elimination (CSE) method proposed by Jang et al. (2002) does not guarantee hardware reduction over the conventional horizontal CSE method in practical linear phase finite impulse response (LPFIR) filter implementations. A method to implement FIR filters with a minimum number of adders by efficiently combining horizontal and vertical common subexpressions is proposed.
