SYSTEM DESIGNING AND MODELLING USING FPGA
Abhinav Deshpande · 2014
This paper presents the overview of an FPGA system in which different complex arithmetic and logical operations are performed by using a set of programmable and reconfigurable arrays of various logic gates and the task of performing a single operation is distributed equally to a set of given number of gates and the system is provided with a clock generator which provides the necessary timing and control to the system with the help of an external oscillator which is set to a given desired frequency. A set of instructions which is called as program is written to execute a certain task which is required to perform a single part of a given set of operations to be performed by the electronic circuit. The language of programming like Very High Speed Integrated Circuits Hardware Description Language (VHDL) and Verilog is used to program a logic gate like AND, OR, NOT, NAND, NOR, EX-OR gates and the study of different modules is done to understand the working of the programming language in order to gain preliminary knowledge about the syntax and instructions which constitute the base of any digital system. A basic knowledge about the language and its structured components like hardware modules and the commands is essential to acquire a general hold over the understanding of FPGA.
