Floating Point Adder and Multiplier

The FP Adder is a single-precision, IEEE-754 compliant, signed adder/substractor. It includes both single-cycle and 6-stage pipelined designs. The design is fully synthesizable and has been tested in a Xilinx Virtex-II XC2V3000 FPGA, occupying 385 CLBs and with a theoretical maximum operating frequency of 6MHz for the single-cycle design and 87MHz for the pipelined design. The design was tested at 33MHz.

The FP Multiplier is a single-precision, IEEE-754 compliant, signed multiplier. It includes both single-cycle and 4-stage pipelined designs. The design is fully synthesizable and has been tested in a Xilinx Virtex-II XC2V3000 FPGA, occupying 119 CLBs and with a theoretical maximum operating frequency of 8MHz for the single-cycle design and 90MHz for the pipelined design. The design was tested at 33MHz.
