Techniques for reducing power consumption in digital circuits that underly automatic control of modern engineering systems are of paramount importance due to the simultaneously growing demands for portable multimedia devices and energy conservation. Digital filters, being ubiquitous in such devices, are thus a prime candidate for low power design. We review an algorithmic approach to low power frequency-selective digital filtering, an essential ingredient for energy efficient technological innovation in many domains.

Filter Structures

Techniques for reducing power consumption in digital circuits have become increasingly important because of the growing demand for portable multimedia devices. Digital filters, being ubiquitous in such devices, are a prime candidate for low power design. Algorithmic approaches to low power frequency-selective digital filtering which are based on the concepts of adaptive approximate processing have been developed and formalized by introducing the class of approximate filtering algorithms in which the order of a digital filter is dynamically varied to provide time-varying stopband attenuation in proportion to the time-varying signal-to-noise ratio (SNR) of the input signal, while maintaining a fixed SNR at the filter output. Since power consumption in digital filter implementations is proportional to the order of the filter, dynamically varying the filter order is a strategy which may be used to conserve power. In this paper we introduce a class of approximate filter structures using FIR digital filter constituent elements. These filter structures are explored and shown to be an important element in the characterization of approximate filtering algorithms.

Battery Technology

Majority of the devices that are used in ubiquitous computing are expected to be as small as possible, be able to perform as many computations as possible, and transmit the results to another device or computer. Such expectations in performance put a pressure on the power budget of such devices. It is a well-known fact that the advances in battery technology are much slower and cannot keep up with the performance demands of tiny gadgets unless new methods of designing and managing hardware and software are developed and used. This chapter will introduce the motivation for low power design considerations by discussing the power limitations of ubiquitous computing devices. Then the chapter will discuss the research directions that are being pursued in literature for reducing power consumption and increasing efficiency of ubiquitous computing systems.
