Asynchronous Chip

Abstract - Ppt : Breaking the bounds of the clock on a processor may seem a discouraging work to those brought up through a general engineering program. Without the clock, how do you arrange the chip and know when you have the correct data ? We may have to take this task on very fast. Clock speeds are now according to gigahertz range and there is not much room for speedup before physical realities start to difficult things. With a gigahertz powering a chip, signals barely have enough time to make it across the chip before the next clock tick. At this point, speed up the clock frequency could become harmful. This is when a chip that is not constricted by clock speed could become very valuable. The idea of designing a computer processor without a central controlling clock is not a new process. In fact, this idea was suggested in early 1946, but many engineers felt that this asynchronous design would be very difficult to design with their current, and by today’s standards, complex technology. Nowadays, we have the modern manufacturing devices to make chips extremely perfect. Due of this, it is possible to create prototype processors without a clock. But will these chips catch on? A major problem in the development of clock less chips is the competitiveness of the computer industries. Presently, it is nearly impossible for companies to develop and manufacture a clock less chip while keeping the cost low.
