Abstract :
Multiview video coding (MVC) systems require much more bandwidth and computational complexity relative to mono-view video systems. Thus, when designing a VLSI architecture for MVC systems, the hardware resource allocation is a critical issue. In this paper, we propose a new system bandwidth analysis scheme for various and complicated MVC structures. The precedence constraint in the graph theory is adopted for deriving the processing order of frames in a MVC system. In addition, current block centric scheduling (CBCS) and search window centric scheduling (SWCS) are proposed for MVC bandwidth analysis. By adopting data reuse schemes, several design points are explored with the aid of the proposed analysis scheme. The suitable hardware resource allocation can be easily determined.
