Demonstration of the Benefits of Asynchronous vs. Synchronous Circuits

Asynchronous circuits hold several advantages over synchronous designs.Currently, the asynchronous technology field is small, but it is expected to grow significantly over the coming years.Hence, it is important to show the advantages of asynchronous designs to help aid its growth.Asynchronous circuits display tolerance to temperature and supply voltage variation.A direct comparison of these attributes can be shown by having a synchronous and an asynchronous microprocessor play a song and then introduce various stresses.Under testing the asynchronous microprocessor sped up when introduced to cold and slowed down when heat was applied.Lowering the supply voltage caused the asynchronous microprocessor to slow down.The synchronous processor failed in all cases.
