Especially in linguistic approaches to language acquisition, the role of language processing has not been prominent. With few exceptions (e. g. Goodluck and Tavakolian, 1982;

Introduction,ry to enlarge chip functionality. Already in 1965 Gordon Moore predicted that the total number of devices on a chip would double every year until the 1970s and every 24 months in the 1980s. This prediction is widely known as “Moore’s Law” and eventually culminated in the Semiconductor Industry Assoc

Power Versus Energy, this issue in a complete way, power as well as energy consumption should be taken into account. Although power and energy are related via a straightforward time integral, the impact on a system when constraining it via power or energy consumption, can be completely different. Power is regarded when

Reduction of Functional Power Dissipation,ear that logical reversibility and quasi-statical changes of states are necessary boundary conditions for physical reversibility. All practical systems are physically irreversible, because they either consist of reversible logic and are non-quasi static or they consist of irreversible logic. Moreove

In this chapter solutions to reduce the leakage power and the short-circuit power will be discussed in section 5.1 and 5.2, respectively. In battery operated applications power dissipation caused by weak-inversion curre

This chapter will focus on weak-inversion current reduction techniques. Existing and new weak-inversion reduction techniques pass in review. To find new reduction techniques
