Lecture 4: Logic Design -- Sequential Circuits

Representing sequential circuits (text, sec. B.6)

Finite state transition network
Transition table
In a transition table, the input columns represent the state of the circuit and the inputs to the circuit; the output columns represent the next state of the circuit.
Designing a sequential circuit

MIPS architecture

We will base our computer design on the MIPS architecture (text, chapter 3).  Its simple structure allows for relatively simple machine designs. Sharp contract with CISC (complex instruction set) architectures such as the Intel 80x86 (sec. 3.12) Will return to performance issues later in semester
