Knowles adder
WebJul 31, 2024 · For adder modules, more than size 16-bit, fan-out is a problem with Skylansky structure. The wiring may be complicated if Kogge-Stone structure is used because of dual-rail nature of adiabatic logic. Hence, for larger sized adders, higher radix extension of Knowles adder is used. So, radix-four 64-bit CLA is considered in this work. WebSklansky, Kogge-Stone, and Knowles adder architectures. The method of Logical Effort [15] builds on the RC delay model to offer a convenient shorthand for understanding the effects of fanout and gate sizing on delay. Dao and Oklobdzija [5, 6] applied this method to a few adders and concluded that logical

Webchosen: Ladner-Fisher adder, Knowles adder and Kogge-Stone adder. They spread over the range of area-speed tradeoffs in prefix adder design [8]. These adder architectures are shown in Figure 1, 2 and 3, respectively. All graphs are drawn in the traditional prefix description style: black nodes depict nodes performing computation WebB. Knowles adder Knowles adder makes a trade off between logic depth and interconnect area. Knowles adder. This adder is similar to Kogge Stone adder [13]. The only difference is that the last stage wiring complexity is reduced to half. The drawback of Kogge Stone adder implementation is routing complexity and larger area consumption. Figure-3 ...
