The digital design is a very broad field. Its applications can be found in our daily life such as in laptops, calculators, cameras etc. The VHDL has become an essential tool for designers in the world of digital design[1]. This paper presents the VHDL implementation of a 32-bit microprocessor. The structural VHDL model of the microprocessor is designed to perform 16 operations which include both logical and arithmetic operation. Here the microprocessor is divided into various sub-modules and each of them was programmed using VHDL. The VHDL implementation and functionality test of the 32-bit microprocessor are done by using the Xilinx tool.
