3. Our Project Description Objective Objective –To design a chip for a SCUBA diver that does real-time calculations to warn the diver of safety concerns including decompressions sickness and lung overexpansion Goals Goals –small, dense design –good aspect ratio –Low power Slides: 1 Presenter: Karolina

4. Marketing Stuff… What is SCUBA diving? What is SCUBA diving? World market for diving – statistics World market for diving – statistics The dangers and hazards of diving The dangers and hazards of diving The use of dive tables The use of dive tables Why a dive computer is a better alternative Why a dive computer is a better alternative Why OUR dive computer is better than the others Why OUR dive computer is better than the others Slides: 5-6 Presenter: Karolina

5. Our Design Flow Discussion of nitrogen absorption math Discussion of nitrogen absorption math Description of the architecture and flow of each of the 8 modules Description of the architecture and flow of each of the 8 modules Overall architecture and flow Overall architecture and flow Slides: 11 Presenter: Steve

6. The Design Process Architecture Architecture –ROMs for TTF and TL –Pressure Calculator – difference equation Layout Layout –Pressure Calculator Combined a lot of modules to make the wiring do-able Combined a lot of modules to make the wiring do-able –Time to Flight and Time Left Bit-slice approach made the layout easier and smoother Bit-slice approach made the layout easier and smoother Simulations Simulations –AAAH!!! Slides: 2-3 Presenter: Steve
