Work Plan
1. Individual Work
• Christopher Boyd
(1) Initial Objectives
Each button will correspond to a specific octave.
The synthesizer will take the music file and output
the music in the specified octave to the speaker.
PWM will be used for the audio output.
(2) Secondary Objectives
Playing multiple octaves at once.
Extra: Playing the music at different tempos.
Display note currently being played.

Description
Store music file
Transfer Music file to bit file
and download to ROM
Read music file
Read ROM by different bit size
(example :
2~3 bits  Octave information
16 bits  Note information
3 bits  Durational information )
(2)Extra Function

SUMMARY AND CONCLUSIONS
• The initial goal of this project is to synthesize music
with four-part harmony.
• This will require being able to play notes in four
different octaves as well as a memory controller to
store the song data.
• Extra hardware is required to play music with the
Spartan-3 Starter Kit. Therefore, we [will use
Spartan-3A Board to support PWM audio output
from the FPGA.]
