The H.264/AVC intra-only frame encoder, for its excellent encoding performance, is well-suited for image/video compression applications such as Digital Still Camera (DSC), Digital Video Camera (DVC), television studio broadcast and surveillance video. The forward integer transform is an integral part of the H.264/AVC video encoder. In this paper, for image compression applications running on battery-powered electronic devices (such as DSC), the authors propose a low-power, area-efficient realization of the forward integer transform. The proposed solution reduces the number of operations by more than 50% (30 vs. 64) and consumes significantly less dynamic power when compared with existing state-of-the-art designs for the forward integer transform.
