Many companies have tried to gain a competitive advantage in the marketplace by shortening their development cycles and rushing products to market. However, some computer industry observers say this has led to buggy products, aberrant development ...

Research groups, large businesses, government agencies and other organizations are using improved data mining technologies and techniques to discover meaningful patterns in huge databases, and now, data mining has been refined to the point where even ...

The exchange of goods conducted face-to- face between two parties dates back to before the beginning of recorded history. Traditional means of payment have always had security problems, but now electronic payments retain the same drawbacks and add some ...

The most important physical trend facing chip architects is the fact that on-chip wires are becoming much slower relative to logic as the on-chip devices shrink. The author points out that it will soon be impossible to maintain one global clock over the ...

A quantum leap in a compiler's ability to automatically extract parallelism from code would have enormous ramifications for future architectures, although the issue of compatibility with legacy software also hinders architectural innovation. The author ...

Workloads drive architecture design and will change in the next two decades. For high-performance, general-purpose processors, there is a consensus that multimedia will continue to grow in importance. The authors predict these processors will ...

Researchers from the University of Michigan conclude that billion-transistor processors will be much as they are today, but just bigger, faster, and wider (issuing more instructions at once). The authors describe the key problems (instruction supply, ...

Based on their research at Carnegie Mellon University, these authors also argue for billion-transistor uniprocessors. Like Patt et al., they divide the important implementation problems into three components: instruction flow, register dataflow, and ...

T his article proposes a new architecture called "trace processors," which consist of multiple, distributed on-chip processor cores, each of which simultaneously executes a different trace. All but one core executes the traces speculatively, having used ...

These Stanford University researchers present the case for billion-transistor processor architectures that will consist of chip multiprocessors (CMPs): multiple (four to 16) simple, fast processors on one chip. In their proposal, each processor is ...

The most radical of the architectures that appear in this issue are Raw processors-highly parallel architectures with hundreds of very simple processors coupled to a small portion of the on-chip memory. Each processor, or tile, also contains a small ...

As we more fully enter the information age, technology is creating new competitors and new strategic options for business. Moreover, as operations become more critical in a world with shorter product cycles and lead times, the importance of integrated ...

Early in the history of programming, brilliant people realized that every good software system has some desirable properties: It should be extensible; parts of it should be modifiable without major impact on other parts; and so on. Because of the ...
