Dynamic Range, Stability, and Fault-tolerant Capability of Finite-precision RLS Systolic Array Based on Givens Rotations
(1990)
The QRD RLS algorithm is generally recognized as having good numerical properties under finite-precision implementation. Also, it is very suitable for VLSI implementation since it can be easily mapped onto a systolic array. ...
Optimal Unified Architectures for the Real-Time Computation of Time-Recursive Discrete Sinusoidal Transforms
(1993)
An optimal unified architecture that can efficiently compute the Discrete Cosine, Sine, Hartley, Fourier, Lapped Orthogonal, and Complex Lapped transforms for a continuous input data stream is proposed. This structure uses ...
Unified Parallel Lattice Structures for Time-Recursive Discrete Cosine/Sine/Hartley Transforms
(1991)
The problems of unified efficient computations of the discrete cosine transform (DCT), discrete sine transform (DST), discrete Hartley transform (DHT), and their inverse transforms are considered. In particular, a new ...
VLSI Algorithms and Architectures for Time-Recursive Discrete Sinuoidal Transforms with Applications to Real-Time Video Communications
(1992)
In this dissertation, we address the problem of developing efficient VLSI algorithms and architectures for discrete sinusoidal transforms in real-time applications for video communication systems. The major difficulty of ...

VLSI Implementation of Real-Time Parallel DCT/DST Lattice Structures for Video
(1992)
The alternate use [1] of the discrete cosine transform (DCT) and the discrete sine transform (DST) can achieve a higher data compression rate and less block effect in image processing. A parallel lattice structure that can ...
Real-Time Parallel and Fully-Pinelined Two-Dimensional DCT Lattice Structures with Application to HDTV Systems
(1991)
The two-dimensional discrete cosine transform (2-D DCT) has been widely recognized as the most effective technique in image data compression. In this paper, we propose a new algorithm to compute the 2-D DCT from a ...
