This paper involves the design and simulation of 16 bit microprocessor architecture on FPGA using VHDL. Significant features such as the , increased speed ,minimal implementation real-estate, reduction in power and maximum configurability are provided by several FPGAs. Where earlier a design may have included 6 to 10 ASICs, but today the same design can be achieved using only single FPGA.VHDL is used in order to programme FPGA.VHDL is an acronym for very high-speed integrated circuit hardware description language. This model actually represents the textual description of a hardware design or a piece of design which, when simulated mimics the design behavior .The processor contains a number of basic modules. These modules are register array of 8X16 bit register, an ALU, shift register, program counter , an instruction register ,an address register, a comparator and control unit. All of these units or modules are assembled together and communicate through a common 16 bit tristate data bus.
