چکیده
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. key words: Quality-Driven Design, Variable Analysis, Design Reuse, Application-Specific Optimization

Video Quality Modeling for Quality-driven Design
This paper models the video quality, which focuses on the effects of computation precision by combining subjective-objective metric. The motivation behind the research is to bring quality-driven design into effect for video applications. We change the computation-precision of IDCT, the kernel program of MPEG-2 video decoder and get the experimental computation-precision-oriented video quality m...
