Abstract :
The paper presents a high performance implementation of asynchronous ALU on FPGA by minimizing the amount of time taken for the execution of instructions. The amount of time taken for the execution have been minimized using a modified version of 4 phase handshaking protocol. The asynchronous design methodology helps to achieve higher flexibility and performance of the arithmetic logic unit. The ALU has been implemented on Xilinx ISE simulator and Spartan 3E family FPGA board.The speed of the computation has been increased to 1.56 times the speed with the previous available asynchronous versions with the help of modified 4-phase handshaking protocol.
