Frequencímetro utilizando FPGA

Abstract

The FPGA is a programmable logic circuit consisting of logic blocks organized in highly reconfigurable matrix patterns, allowing the user to control the functions to be executed according to the need. This can be associated with a hardware description language for very high-speed integrated circuits, which allows the processes to be executed concomitantly, which frees the programmer from worrying about the order of processes throughout the code. In this work the educational kit DE2 of Altera © was used, belonging to the family of programmable boards in FPGA, making a project flow record for implementation of a frequency monitoring instrument.
