Fast digital operational units using comparison lookahead
J.-Y. Han · 2003
The author discusses the design of two-input maximum operation units (TIMUs) using comparison look-ahead, as well as the different possible designs for multiple input max/min units (MIMUs). The time and area complexities of different designs of MIMUs and TIMUs are discussed and compared. It is found that the implementation of MIMU as a binary tree of high-speed look-ahead TIMUs gives a shorter time of selection than the selection-sort-based MIMU for a practical number of inputs. However, the former is much more expensive in area.>
