The growing demand in multimedia video processing and its applications owes its origin to and, at the same time, is responsible for the further development of both hardware design and software techniques.
Aided by advancements in very large-scale integrated circuit (VLSI) manufacturing technology that has made possible the integration of increased functionality in smaller circuits, it is primarily the development of novel signal-processing architectures and design techniques that has brought audio, video, graphics, image, speech, and text processing together.
It has also prompted advanced multimedia video applications such as high-definition digital television, digital set-top boxes with time-shift functionality, 3D games, H.26x video conferencing, MPEG-4 interactivity, and so forth.
The computational requirements of multimedia video processing being dominated by signal-processing tasks that require complex and real-time processing on high volumes of data, this chapter attempts to take a closer look at some of the recent trends in designing integrated circuits (ICs) for such systems.
