Figure 7From: Parallel progressive multiple sequence alignment on reconfigurable meshesA 4-way max switch. A configuration of a 4-way max switch to solve the longest common subsequence (lcs). The South-East processing unit (in bold) configures {NS,E,W} if the symbols at row i and column j are different; otherwise, it configures{N,E,SW}. This figure show a configuration when the two symbols are different.Back to article page
