Abstract :
This paper describes the behavior of the synthesis of several adders with different structures: lineal, like ripple carry adder, tree, like carry look ahead; array, like prefix adders; and optimized low level logic over FPGAs. The results of used resources and total delay of the resulting circuit are compared over the commercial families VIRTEX4 and STRATIX2 from Xilinx and Altera manufacturers, respectively
