Implementation of 32-Bit Arithmetic Logic Unit on Xilinx using VHDL

Abstract

In the present day knowledge, there is an massive requisite of developing appropriate data communication interfaces for real time embedded systems. Field Programmable Gate Array (FPGA) gives various means, which can be programmed for constructing an effective embedded unit. The FPGA configuration is generally specified using a hardware description language (HDL). VHDL (VHSIC hardware description language) is a hardware description language used in electronic design automation to explain digital and mixed-signal structures such as field programmable gate arrays (FPGA) and integrated circuits. This work proposes a technique to design and implement a 32 bit ALU which is a digital circuit that performs arithmetic and logical operations on Xilinx ISE using VHDL.
