VHDL environment for floating point arithmetic and logic unit design using pipelining is introduced; the novelty in the ALU design. Pipeling provides a high performance ALU. Pipelining is used to execute multiple instructions simultaneously. In top-down design approach, four arithmetic modules, addition, subtraction, multiplication and division are combined to form a floating point ALU unit. Each module is divided into sub- modules. Two selection bits are combined to select a in the ALU design are realized using VHDL, design functionalities are validated through VHDL simulation. Synthesis and simulation result find out in the Xilinx12.1i platform.
