  1. Pooya Khorrami Yush Gupta Ross Finman Evan Mullinix MAT

  2. Status Update • Building an electronic party game played on a mat • Finishing construction • Implemented and tested basic i/o functionality • Music sampling/pwm • Built so far: • 1 Epic circuit • 16 Silicone pads w/embedded LEDs (4) • 16 Plastic rims • 1 Hardboard mat comprised of 4 hinged panels and 16 total contact points for the pads

  3. Experimentation Plan • Latency • Pad color update time • Full game cycle time (input, compute, update) • Throughput • Pad reads/sec • Full game cycles/sec • Experiment to find latency and throughput • Test: read pad inputs, compute new pad colors, write out new pad colors • Tektronix TDS 3064B (in Robotics Club) • Synthetic workload but is representative of typical system tasks

  4. Initial Data – Input micro benchmark

  5. Initial Data – Output micro benchmark

  6. Initial data – macro benchmark

  7. Looking Forward • Lessons Learned: • Construction can get very involved • Debugging difficulty does not vary linearly with circuit size • Use wall power to avoid fanout issues and low resistor values to maximize LED brightness • What’s next: • Mount plastic rims to mat • Connect all hardware to the epic circuit at once to test system as a whole • Finalize game code • User testing
