Asynchronous Sequential Circuits
LEARNING OBJECTIVES
After studying this chapter, you will know about:
- Fundamental mode circuits and pulse mode circuits.
- Design steps.
- Pitfalls, remedies and essential hazards.
- Cycles, critical and non–critical races.
- Asynchronous pulse counters.
We encounter many situations when synchronising clock pulses are not available. For example, counting visitors to a library, counting cosmic particles or meteors impinging on earth's atmosphere are asynchronous phenomena. Furthermore, asynchronous circuits are generally faster than synchronous circuits as the speed of the latter is limited by the clock. At times, a large synchronous system may allow some of its subsystems to operate asynchronously in order to ...
