Capstone – A Traffic-Light State Machine: State Table, Combined Keys, 24 Clock Ticks and the Fastest Clock
This lesson is part of the course
In this lesson
You run a toy pedestrian-crossing controller as a state machine for 24 clock ticks – next state from a state table via a combined key, outputs per state – then add up the path delays and find the highest clock frequency the timing allows.
