DESIGN AND IMPLEMENTATION OF HIGH SPEED HYBRID ADDER WITH REVERSE CARRY PROPAGATE ADDER
This paper helps us to discuss about approximate Reverse Carry Propagate Adder (RCPA), In RCP adders the carry signal propagates in counter down flow manner. I.e. it flows from the maximized prioritized bit to the least prioritized bit. Henceforth the carry i/p signal has the greater significance then the o/p carry. This way of carry propagation increases the steadiness in presence of delay versions, here in this paper we are discussing about the three different designs of RCPA cells with different delay, energy, and accuracy configurations, and also we use a few hybrid structure within the n bit adder design were least half of the adder design is carried out with this RCPA and most considerable half will be introduced by way of using some accurate high pace adder like KoggeStone adder that may decorate the adder speed. The Hybrid adders realized utilizing those systems are studied and as compared people with conventional approximate adders with Xilinx ISE 14.7 Verilog HDL coding.
