A reconfigurable hardware for one bit transform based multiple reference frame Motion Estimation
—Motion Estimation (ME) is the most computationally intensive part of video compression and video enhancement systems. One bit transform (1BT) based ME algorithms have low computational complexity. Therefore, in this paper, we propose a high performance reconfigurable hardware architecture of 1BT based multiple reference frame (MRF) ME. The proposed ME hardware architecture performs full search ME for 4 Macroblocks and 4 reference frames in parallel. The proposed hardware is faster than the 1BT based ME hardware reported in the literature even though it is capable of searching in 4 reference frames. MRF ME increases the ME performance at the expense of increased computational complexity. The reconfigurability of the proposed ME hardware is used to statically configure the number and selection of reference frames based on the application requirements in order to trade-off ME performance and computational complexity. The proposed hardware architecture is implemented in Verilog HDL. The...
