Microelectronic Systems--University of Tennessee 5 5 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.

Cooperate Work Co-Work Start Date - Expected Date : 11/02 (After Basic Function is Ready) 11/12 - 1’st Due for the Basic Deadline Prepare Demo with Single Scale & Song 12/02 – 2’nd Due for the Final Deadline Prepare Demo with Multiple Scales & Songs

Microelectronic Systems--University of Tennessee 8 8 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.]
