5.Asynchronous Systems

The past decade has seen tremendous advancement in the design of computer systems. Every year the speed and amount of integration of the processors is increasing exponentially, as per one of the most famous technology predictions of our times: known as Moore’s Law (Dr. Gordon Moore, Cofounder of Intel).
The amount of power dissipation in a chip is also increasing rapidly. Within a decade, the power dissipation in processors as per the current technology will reach to the maximum controllable limits. Reduced power consumption is also very important as we embed computing devices in portable electronic devices. Clockless or asynchronous design methodology is one solution, which can give better performance with reduced power consumption compared to current synchronized to a global clock. So there is no dynamic power consumption. Also, they give "average-case" performance instead of "worst case" performance as in synchronous systems. Thus, asynchronous systems are faster than their synchronous counter parts. The current synchronous design techniques won't be able give optimum results for future processors. A synchronous systems with their improved performance and reduced power consumption are the best alternative currently available for such systems involving intensive computations, portable compact systems etc. This seminar report attempts to bring out the concept of clockless computing and their merits over current computing techniques, which equip it to replace current techniques in near future.
