A Complete Pipelined Parallel CORDIC Architecture for Motion Estimation

چکیده
We propose a novel fully-pipelined parallel CORDIC architecture (CORDIC-DXT-ME) employing the DCT PseudoPhase Techniques for Motion Estimation. Its low computational complexity, O(N2) as compared with O ( N " ) of BKlI ME; makes it fascinating in real time applications. In addition, the DCT-based nature enables us to replace all multipliers by CORDICs with simple shift-and-add operations and t o incorporate its implementation with the DCT codec design to gain further savings in hardware complexity. The architecture is regular, modular, and has solely local connection and is suitable for MPEGB compatible video codec design on a dedicated single chip.

In this paper, a novel fully pipelined parallel CORDIC architecture is proposed for motion estimation. Unlike other block matching structures, it estimates motion in the discrete cosine transform (DCT) transform domain instead of the spatial domain. As a result, it achieves high system throughput and low hardware complexity as compared to the conventional motion estimation design in MPEG standa...

We present the design of parallel architectures for the computation of the Hough transform based on application-specific CORDIC processors. The design of the circular CORDIC in rotation mode is simplified by the a priori knowledge of the angles participating in the transform and a high throughput is obtained through a pipelined design combined with the use of redundant arithmetic (carry save ad...
متن کاملA highly accurate pipelined architecture for a CORDIC ARMA lattice filter
This paper presents a method to improve implementation accuracy of a recently proposed CORDIC ARMA lattice filter. Since the CORDIC ARMA lattice filter algorithm has a problem in its shift sequence, i t cannot implement a lattice filter accurately. Therefore, in this paper we apply the shift sequence proposed by Walther without the problem to the CORDIC ARMA lattice filter, and then we realize ...
