Microprogramming

• functional bits, what they do
• structure of a microprogram word,
  • sequencer part
  • conditions
  • exceptions
  • ALU part
  • address part
  with an explanation, which parts are controlled and how
• vertical migration, coding of functional bits, nanoROMs - $\rightarrow$ important for the new VLIW processors, e.g., HP
• microprogramming at an example of AMD chips - (implementation of basic instructions, like division, multiplication, branch commands) Harvard versus von Neuman architecture (advantages/disadvantages)
