Quality-Driven Design for Video Applications
Yun Cao, Hiroto Yasuura · Kyushu University Institutional Repository (QIR) (Kyushu University) · 2002
This paper presents a novel system-level design methodology, called quality-driven design, by which applicationspecific optimization can be achieved; furthermore the entire functionality can be shared to maximize design reuse. As a case of study, this paper focuses on quality-driven design for video applications and introduces an output quality adaptive approach based on variable bitwidth optimization to explore a new design space. MPEG2 video is used as the driver application to illustrate the potential of the presented methodology. Experimental results show the effectiveness of the methodology.
