ABSTRACT
Recently low-power design has become a very important and critical issue to enhance the portable multimedia market. Therefore, various approaches to explore low power design have been made. The implementation can be categorized into system level, algorithm level, architecture level, circuit level, and process/device level. Figure 19.1 shows the relative impact on power consumption of each phase of the design process. Essentially higher-level categories have more effect on power reduction. This section describes the impact of each level on low-power design.
