摘要

Within the European Emphasis project, the architecture of a co-processor for MPEG-4 video rendering has been specified. This co-processor has a dedicated unit that performs the inverse perspective transform of video objects for final frame composition. This paper presents a complete study of computation accuracy and proposes a possible architecture for hardware implementation.
