It used four-tree recursive method to reduce critical path, instead of traditional part product carry-in chain to generate high part of long-latency multiplier. Then it reduced hardware cost by branch breaking and combing to implement logic share between tree structures. Also it supported auto-synthesize within different area constraints. This new multiplier gets 10% faster than the one based on Booth arithmetic and Wallace tree. %K carry chain %K delay %K four-tree %K branch combining %K branch breaking %K tree traversal
