ABSTRACT
Clockless chips are electronic chips that are not using clock for timing signal. They are implemented in asynchronous circuits. An asynchronous circuit is a circuit in which the parts are largely autonomous. They are not gov ....etc

Introduction


DNA chips also known as micro arrays are very significant technological development in molecular biology and are perhaps most efficient tool available for functional genomics today. An evident from the name micro array essentially consists of an array of either Oligonucleotides or cDNA fixed on a substrate. There has been an explosion of information in the field of genomics in the last five years. Genomes of several organisms have been fully sequenced. The next step necessarily involves the analysis of comparative expression l ....etc

Space is a hostile environment. No atmosphere, extreme variations in temperature and almost no energy sources, where even the slightest of mistakes can lead to a disaster. The vast emptiness of space is filled with radiation, mostly from the sun.

A normal computer unless given proper shielding will not be able to work properly. Thus special types of chips- rad hard chips are used.

Radiation hardened chips are made by two methods: -
Radiation hardening by process (RHBP)
Radiation hardening by design (R ....etc

Today's microprocessors sport a general-purpose design which has its own advantages and disadvantages. ? Adv: One chip can run a range of programs. That's why you don't need separate computers for different jobs, such as crunching spreadsheets or editing digital photos ? Disadv: For any one application, much of the chip's circuitry isn't needed, and the presence of those wasted circuits slows things down. Suppose, instead, that the chip's circuits could be tailored specifically for the problem at hand--say, computer-aided design--and then rew ....etc

Definition

Computer chips of today are synchronous. They contain a main clock, which controls the timing of the entire chips. There are problems, however, involved with these clocked designs that are common today.One problem is speed. A chip can only work as fast as its slowest component. Therefore, if one part of the chip is especially slow, the other parts of the chip are forced to sit idle. This wasted computed time is obviously detrimental to the speed of the chip.

New problems with speeding up a clocked chip are just around the corn ....etc
