I write this summary for personal learning purposes.

Agenda for Today

• Instruction Set Architectures (ISA): LC-3 and MIPS
• Assembly programming: LC-3 and MIPS
• Microarchitecture (principles & single-cycle uarch)

Microarchitecture

An implementation of the ISA. There can be many implementations of the same ISA (i.e., MIPS R2000, R10000, Intel 80486, Pentium, …)

• The Von Neuman Model
• The Dataflow Model

Implementation of the ISA under specific design constraints and goals. Anything done in hardware without exposure to software. (Pipelining, In-order versus out-of-order instruction execution, Speculative execution, Voltage/frequency scaling, …)

A Single-Cycle Microarchitecture (A Closer Look)

Youtube, pdf p.57.

Single cycle data path and control signals.
