Algorithmic State Machine Charts

LEARNING OBJECTIVES

After studying this chapter, you will know about:

  • Usefulness of algorithmic state machine (ASM) charts in the design of control logic in digital machines.
  • Elegance in writing the Boolean function by inspecting the ASM chart.
  • The Differences between Data processor and Control circuit and the interconnections.
  • Differences between conventional flow chart and ASM chart.
  • The importance of using the various design techniques for control depending on the complexity.
    1. Conventional design using gates.
    2. Design using Multiplexers
    3. PLA control.

Just as a flow chart serves as a useful aid in writing software programs, Algorithmic State Machine (ASM) charts help in the hardware design of digital ...
