Design Decisions

• Transistor estimation done assuming 8-bit bus
  width
• Memory / Registers not considered
• Basic Matrix Multiplier and Divider structure
  assumed

Problems Questions

• Pushing the transistor count cap
• Memory and registers not considered
• Hardware implementation of xn and -1 not
  obvious
• Circuit may be a 'novelty' at only 8 bits
