Programmable Music Visualizer ChecklistDany Qumsiyeh Mike SpindelDecember 5, 20051 Audio PreprocessingThe audio preprocessing stage will take input from the AC97 microphone inputand make it available to the effects generators via sample memory. This will bedemonstrated by the ”waveform” effects generator. If time permits, the preproces-sor will also perform beat detection and FFT and make this data available to thevisualizer. These features will be demonstrated by appropriate visualizations.2 CPU1. Show register file with parameter outputs in simulation.2. Show instruction memory fetch working in hardware.3. Show control logic and timing in simulation.4. Demonstrate register operations through an ALU.3 Effects BoxThe effects box will perform the following things:1. Generate coordinates via the pixel FSM.2. Have a configurable transform box. This will implement at least the rotatetransform and the modulo transform. These will be demonstrated visually.3. Implement at least two effects generators, including a waveform generatorand a fetch from the previous frame memory. These will be demonstratedvisually.14. Have a configurable blend stage. This will be demonstrated visually.If time allows, the effects module will also implement a configurable convolu-tion stage, more generators, and more translate types.4 Display1. Show reliable ZBT read and write operation, with test code or video output.2. Show VGA video output, accounting for pipelining delay, with test code orfrom ram.3. Show oldframe memory access interleaving module, in simulation or videooutput.4. Show newframe interleaving and pipelining module, in simulation or videooutput.5. Demonstrate video being updated through double-buffer
