Keshab K. Parhi · 1997
In a few years, multimedia will become part of everyone's life. This paper presents an overview of DSP processors which are targeted for multimedia applications. Current and future trends of these processors are predicted. Reduction of power consumption in these systems is one of the major challenges for implementation. Various techniques for reduction of power consumption are reviewed. 1. Introduction The last decade has seen tremendous growth in the field of communication and computing. Much of this growth has been fueled by the promise of multimedia - an exciting array of new products and services, ranging from video games, car navigators, web surfing, to interactive television, cellular and video phones, personal digital assistants, video on demand, and desktop video conferencing. In addition to conventional user interfaces and I/O operations, these multimedia applications demand real-time digital signal processing (DSP) to support compression and decompression of audio, speech, ...
