Summary

This problem-solving session, led by Prof. Onur Mutlu, focuses on finite state machines (FSMs) in digital design. The session begins with a brief review of Moore and Mealy machines, highlighting key differences in output generation and state transitions. The instructor emphasizes the importance of including a reset state and ensuring all states have transitions for all inputs. The first exercise involves designing a Moore FSM that outputs logic 1 when the input sequence (read MSB first) represents a number divisible by 8. The solution uses four states to track the number of trailing zeros, with an assumption that zero is divisible by 8. The second exercise involves simplifying a given Mealy state machine by constructing a truth table, identifying equivalent states (A and D), and removing an unreachable state (C). The session concludes with a brief Q&A and a promise to share notes. The content is well-structured, clear, and suitable for students learning about FSM design and simplification.
