Levels in computer design

• Circuit design (transistors, resistors, etc)

  • Result is in terms of gates, flip-flops etc.

• Logical design

  • Put gates and f-f’s together to build larger blocks (registers,adders, multiplexers etc.)

• Register Transfer

  • Design of the datapath by linking together building blocks under the control of the control unit

• Processor chip description

  • Includes datapath, control unit, on-chip caches, TLB’s etc.

• System description
