Lecture 29: Vertical vs Horizontal Microprogramming: The MIC-2 - 3/31/97

Read pages 193-199 (Section 4.5.1) of Tanenbaum

The MIC-2 architecture.
Comparison of vertical versus horizontal microprogramming.
Review for Exam 2:
- Function of the basic building blocks (multiplexer, decoder, clock, etc.)
- Instruction cycle timing and implementation.
  - Functions are performed in each subcycle of the MIC-1.
  - How to encode MIC-1 instructions.
  - How to implement a MAC-1 instruction in the MIC-1.
- Horizontal versus vertical microprogramming.
- Two pass assembler
  - What happens on each pass?
  - How to assemble MAC-1

SKILL: You should understand the trade-offs between vertical and horizontal microprogram design.
