基于FPGA的硬件電子琴的設(shè)計


摘要：可編程邏輯設(shè)計是近年來在電子設(shè)計領(lǐng)域中出現(xiàn)的一門新技術(shù)，它把復(fù)雜的數(shù)字系統(tǒng)轉(zhuǎn)化為用一兩個可編程邏輯器件即可實現(xiàn)的“片上”系統(tǒng)；把系統(tǒng)的更新?lián)Q代轉(zhuǎn)化為簡單的在系統(tǒng)編程設(shè)計?，F(xiàn)場可編程門陣列(FPGA)是當(dāng)今應(yīng)用最廣泛的可編程邏輯器件之一 。

本文介紹了一種基于FPGA的硬件電子琴的設(shè)計實現(xiàn)。該系統(tǒng)主要由用Verilog硬件描述語言設(shè)計的核心部件,再配以適當(dāng)?shù)耐鈬娐?，比如按鍵、蜂鳴器以及數(shù)碼顯示管構(gòu)成。用戶可從琴鍵上進行樂曲演奏，數(shù)碼管動態(tài)顯示當(dāng)前音符名稱，具有一定的市場應(yīng)用價值。

Design of Hardware Electronic Piano Based on FPGA

                                                  

Abstract：Programmable logic design is the field of electronic design in recent years’ a new technology emerged, it put into a complex digital system with one or two programmable logic device can be realized in the "on-chip" system; the upgrading of the system transformation a simple design in system programming. Field programmable gate array (FPGA) is currently the most widely used one of programmable logic devices.

This paper introduces the Design and Implementation of the hardware piano based on FPGA. The system consists of the design’s core components using Verilog hardware description language, which together with appropriate external circuitry, such as buttons, buzzer, and a digital display tube form. Users can play music from the keyboard, and the digital tube displays the current note names dynamically, which has some market value.
