Hardware architecture design for visual processing: present and future

This paper presents the present and future trends of hardware architecture design for image and video coding. Fundamental design issues are discussed with particular emphasis on efficient dedicated implementation. Hardware architectures for MPEG-4 video coding and JPEG 2000 still image coding are reviewed as examples, and special approaches exploited to improve efficiency are identified. Further perspectives are also presented to address the challenges of hardware architecture design for future image and video coding.
