Description
Summary:Power dissipation is becoming a limiting factor in the realization of VLSI systems. The principal reasons for this are maximum operating temperature and, for portable applications, battery life. Because of the relatively greater complexity, the power dissipation in digital signal processing (DSP) applications is of special significance, and low power design techniques are now emerging. This paper provides an overview of the techniques and methodologies that have emerged in the past few years for DSP system design. These include techniques for minimizing power at architectural and algorithmic levels including DSP programming issues. In addition, the paper indicates some potential design directions.
