This paper presents a novel system-level design methodology, called quality-driven design for video applications by bitwidth optimization (QDDV). An output quality adaptive approach based on a forward and a backward propagation technique, which are effective bitwidth analysis and output-quality-based bitwidth analysis are also presented for variable bitwidth optimization. In order to illustrate the potential of the proposed methodology, MPEG-2 video is used as the driver application. Experimental results show the effectiveness of the methodology.
