This paper describes a improved version of design of 32 bit adder module and 32 bit of sub- tractor module by using VHDL. Multiplier is the main component in digital signal processing. For designing floating point multiplier, adder and sub-tractor modules are essentially required. The floating point complex multiplication is one of the basic functions used in digital signal processing application, microprocessors and FIR filters. Floating point format is a standard format used almost in all processing elements. The Objective of this paper is to implement the 32 bit binary floating point adder and sub-tractor with minimum delay. The modules required for the design, are coded in VHDL as it is very useful tool. Simulation and functional analysis is done in Xilinx ISE14. 5. It is observed that the delay required for this design is improved as compared to earlier work. .
