AB  - Cross Diamond Search (CDS) is one of the fast search Motion Estimation (ME) 
  algorithm that caters to the requirement of video coding with relatively minimal 
  limitations. It exploits the cross centre-biased motion vector characteristics 
  in real-world video sequences. The performance of the CDS algorithm is relatively 
  better, compared to that other of the fast search ME algorithms which use a 
  number of search points and similar picture quality as parameters. The objective 
  is to build a new architecture with high performance CDS which requires nine 
  Processing Elements (PEs) to obtain the minimum SAD. The proposed architecture 
  was designed to take advantage of the properties of the CDS algorithm. The study 
  has shown that the CDS algorithm with an efficient architecture with minimum 
  number of gates suitable for the ME algorithms in video coding standards could 
  achieve the desired video output. The results observed after implementing comparative 
  performance analysis have shown that the CDS architecture occupies 23% of logic 
  elements, 1% of dedicated logic registers and consumes as low as 84.63 mW power 
  when it is implemented using Altera Quartus II FPGA device.
