The square brackets are needed to represent the vector. The first number in the square brackets is the sequence number of the first component of the vector, and the second number is the sequence number of the last component of the vector, separated by a colon. The serial number of the vec...
This paper presents a design-for- reconfigurability (DFR) technique for carry look ahead adders (CLAs)[1]. The various adder structures can be used to execute addition such as serial and parallel structures and most of researches have done research on the design...
