An empirical study on standard cell synthesis of elementary function lookup tables
Oscar Gustafsson, Kenny Johansson · 2008
When hardware for implementing elementary functions is discussed it is often stated that for ldquosmall enoughrdquo tables it is possible to just synthesize the HDL description to standard cells. In this work we investigate this fact and show that the resulting cell area primarily depends on the smallest of the number of input and output bits, while the contribution of the larger of the two bit-widths is significantly smaller.
