Nowadays in modern technology, reconfigurable modules are essentially needed to meet a variable accuracy requirement up to 100% in hybrid applications. Hence in this paper, 16-bit carry select adder structure based Variable Accuracy Reconfigurable Adders (VARA1-7) are proposed by using the single bit Reconfigurable Full Adder (RCFA). The RCFA module is based on a structural hierarchy of AND-OR logic and multiplexer logic to reduce power consumption. Further, the performance of the proposed 16-bit adders is evaluated by comparing its speed, area, power, number of variable accuracy output for input with those of the existing carry select adder. Based on the simulation results, the proposed VARA7 shows a high speed, lesser power delay product. But the proposed VARA4 structure consumes 5.67% lesser power consumption and 0.23% lesser power delay product with variable accuracy output up to 100% for an input operand pair at the cost of 5.76% area and 5.5% speed than the existing conventional 16-bit CSLA.
