An Augmented Iterative Array for High-Speed Binary Division

An augmented iterative array for binary division (IAD), is described. It uses carry-save reduction and carry-look-ahead principles to achieve high speed. Logic cost and speed comparisons with two other design techniques are presented. An 8-bit prototype model that operates in under 500 ns has been built from commercially available high-speed MSI TTL integrated circuits to verify the feasibility of the IAD scheme.
