The cost of an impoverished representation
We take a fancy transistor, and use it as a switch
- An inefficient use of transistor dynamics
- Then we build complex functions from switches
- Use many switches
- Each operation needs many switching events
- We pay in efficiency!
- Graph: Energy dissipated by an 8×8 multiplier and by a single transistor
