Overview

• Last lecture

  • Waveforms
  • Class example: F=A+BC
    • Canonical and minimized two-level expressions
    • Schematic (logic) diagrams and waveforms
  • Class example: Implement a word problem
    • A 4-bit prime-number detector

• Today

  • Notation and algorithm for two-level simplification
  • Conversion between two-level forms
    • AND/OR to NAND/NAND or NOR/NOR
    • OR/AND to NAND/NAND or NOR/NOR
  • Class example: Div(4, 5, 6, 7) detector
