WebIt is a Hybrid adder, which consists of generate and propagate blocks as well as the full adders. Path delay is the main concern for these prefix adders. In this Spanning tree adder, “gp” is the generate and propagate block which takes the input bits and produces generate and propagate bits. WebJan 10, 2024 · The number of levels N is reduced to half in each level, hence adder tree structure requires log 2 N levels. As a result, the adder tree structure is faster than the adder array one. In this paper, multi-operand parallel prefix adders based on adder tree structure are designed and implemented in fused MAC unit for reconfigurable systems.
