THE AWESOME GUITAR GAMEProject ProposalEmbedded System DesignCSEE 4840Spring 2012 SemesterAcademic supervisor: Professor Stephen EdwardsLaurent Charignon (lc2817)Imré Frotier de la Messelière (imf2108)Avijit Singh(asw2156)1 IntroductionIn this project, we implement an interactive game where the user can play a dummyguitar to match up the notes as displayed on the screen. The game principle is the sameas in the famous "Guitar Hero" video game series. The expected music will be playedsoftly in the background and will grow louder whenever the user presses the correctkey.2 DesignWe intend to implement the project using an Altera DE2 board, a dummy guitar, aVGA display and a pair of speakers. When the user starts the game he/she will hearthe music. The screen would display a stream of notes. If the user presses the correctbutton at the correct instant, the particular note is added to the music and is playedloudly. To make the user more involved, the display will reflect that the note has beencorrectly played. The implementation will be done on VHDL and C. We plan to have 4buttons on the dummy guitar which would be connected to the GPIOs of the FPGA. Wewill also implement some audio processing to make the game even more entertainingif time permits.3 MilestonesMilestone 1• We will construct the dummy guitar.• We shall detect key inputs with the dummy guitar.• We will play a song (raw sound format) from a SD card in the FPGA.• We will develop a program to build a script of a given song. This means, toproduce a file that contains the notes and their corresponding positions for thisparticular song.• We shall finally make a prototype of the base game engine in Java.Milestone 2• We will work on the sprites and study how to do graphics and how to encode thesound efficiently (how many bits, how many information we can store...).• The Java game prototype will integrate the work on scripts from the first mile-stone.• We shall have designed the game internal functioning to ensure a constant framerate ( on paper).• We will have started implementing the game.2Milestone 3• We shall finalize the game.• We will develop an algorithm to compute the score.• We shall improve the performance of the game and work on the
