What is a logic gate?

Make sure you know how to build a truth table for a diagram with logic gates $($like you did in the Homework $8).$

Make sure you know how to create a diagram when given a truth table $($again$,$ like you did in the Homework $8).$

What is a register? What inputs and outputs does a MIPS register have? Know the purpose of each input and output.

What is a register file? What inputs and outputs does a MIPS register file have? Know the purpose of each input and output.

What is a multiplexor? What inputs and outputs does a MIPS multiplexor have? Know the purpose of each input and output.

What is an adder? What inputs and outputs does a MIPS adder have? Know the purpose of each input and output.

What is an ALU? What inputs and outputs does a MIPS ALU have? Know the purpose of each input and output. We didn$$t discuss ALU control input and zero output, so I$$ll not ask about them.

ALU is arithmetic logic unit.

What is datapath? What is the purpose of a datapath?

What is Control circuitry? What is its purpose?

Be ready to analyse datapath and show how a given instruction is executed in it$.$ Be ready to determine for a given instruction the values of control inputs $($at least those that you analysed in the Homework $8).$

Pipelining was not discussed and will not appear on the final exam.
