Technology Independent Schematic 4.3 Sequential Multiplier 4.3.1. With IP … VHDL code for floating point adder is written in Xilinx 8.1i and its synthesis report is shown in Design process of Xilinx which will outline various parameters like number of slices used, number of slice flip flop used, number of 4 input LUTs, number of bonded IOBs, VHDL Code for a Half-Adder VHDL Code: Library ieee; use ieee.std_logic_1164.all; entity half_adder is port(a,b:in bit; sum,carry:out bit); end half_adder; architecture data of half_adder is begin sum<= a xor b; carry <= a and b; end data; std_logic_1164.all; use ieee. The unit has been coded in VHDL. This Floating Point units were developed as part of the HAVOC project. In the end I used the floating point IP cores, generated with the IP core generator in the ISE. The Floating point packages linked above were actually worthless since the synthesis took like an hour and the maximum frequency was only ~6 MHZ on a Spartan3.
