In addition, the performance edge of the proposed design in both speed and energy consumption becomes even more significant as the word length of the adder increases.doi:10.7603/s40601-013-0046-5Keshav KumarAmit GroverNeeti GroverGstf Journal on Computing...
Furthermore, a new 8-bit full adder is designed based on the majority gate in the QCA, with the minimum number of cells and area which combines both designs to implement an 8-bit adder/subtractor in the QCA. This 8-bit adder/subtractor circuit has the minimum delay and complexity. Being...
An 8-bit adder, operating at 800 MHz, and a single-stage bit-serial adder, running at more than 1 GHz, have been implemented and successfully tested in a standard 1.0 /spl mu/m CMOS process. The performance was achieved through the use of carry-increment full adders, fine-grain pipelinin...

中国大学MOOC: To expand a 4-bit parallel adder to an 8-bit parallel adder, you must把4位并行加
To expand a 4-bit parallel adder to an 8-bit parallel adder, you must把4位并行加法器扩展成8位并行加法器,必须? use two 4-bit adders and with the carry output of one connected to the carry input of the other.使用两个4位并行加法器,并且将其中一个的进位输出端连接到另一个的进位输入端上...
