In this paper, the authors present FPGA-based design of hybrid adder with the optimal bit-width configuration (out of a large number of possible configurations) of each of the sub-adders ...

The Xilinx Virtex-4 family incorporates XtremeDSP building blocks in all three platform FPGA families-the LX, SX, and FX. The SX platforms contain the largest number of 18-bit multipliers, with as ...
