Abstract-Using analytical and simulation results, this paper presents comparative analyses between network on chip and shared-bus AMBA using real application traffic with MPEG-2 video decoder in cycle-accurate realistic simulation environment. We show that despite higher channel latency, NoC has higher bandwidth advantage and outperforms shared-bus AMBA, requiring lower frequency in order to decode the video bitstream at given frame rate.

“…H.264/AVC video coding is the newest standard defined by the Joint Video Team (JVT) [1], [2] in which various techniques have been adopted to obtain a high coding efficiency compared to previous standards. Among the new techniques of H.264/AVC video coding, motion estimation has been introduced to improve the previous video standards such as H.261 and H.263 [1], [2], [3]. Motion estimation for inter prediction is generally performed only on a 16×16 macroblock (MB).…”

“…In addition, intra mode prediction (nine 4×4 and four 16×16 modes) follows inter mode prediction to find the best residual image [1], [2], [4]. For any block mode, the motion vector estimation for a minimum residual image is also performed by full search [3] or fast motion search methods such as a directional diamond search [5] and fast-adaptive rood pattern search [6]. These structures give rise to a complex encoder to be applied in real-time applications.…”

Enhanced Inter Mode Decision Based on Contextual Prediction for P-Slices in H.264/AVC Video Coding

We propose a fast macroblock mode prediction and decision algorithm based on contextual information for Pslices in the H.264/AVC video standard, in which the mode prediction part is composed of intra and inter modes. There are nine 4×4 and four 16×16 modes in the intra mode prediction, and seven block types exist for the best coding gain based on rate-distortion optimization. This scheme gives rise to exhaustive computations (search) in the coding procedure. To overcome this problem, a fast inter mode prediction scheme is applied that uses contextual mode information for P-slices. We verify the performance of the proposed scheme through a comparative analysis of experimental results. The suggested mode search procedure increased more than 57% in speed compared to a full mode search and more than 20% compared to the other methods.

This survey addresses a number of challenges and research areas identified in real time image processing for state-of-the-art hand-held device implementation in networked electronic media. The challenges appear when having to develop and map processing algorithms not only on fading, noisy, and multi-path band limited transmission channels, but more specifically here on the limited resources available for decoding and scalable rendering on batterylimited hand-held mobile devices. Networked electronic media requires scalable video coding which in turn introduces additional degradation. These problems raise some complex issues discussed in the paper. A need to extend, modify and even create new algorithms and tools, targeting architectures, technology platforms, and design techniques as well as scalability, computational load and energy efficiency considerations has established itself as a key research area. A multidisciplinary approach is advocated.
