Time-Recursive Computation, Part II: Methodology, and Application on QMF Banks and ELT
(1993)
Recent advances in ISDN have promoted applications such as video- phone, tele-conferencing and HDTV, that demand real-time processing of large volume audio, video and speech data. Being the only refuge for this intense ...
Design and Implementation of Systolic Architectures for Vector Quantization
(1992)
Vector Quantization has emerged as an efficient data compression tool for compressing speech and image data. We develop efficient systolic architecture implementations of Tree-Search Vector Quantizers (TSVQ) and Finite-State ...
Analysis and Synthesis of Distributed Systems
(1994)
We first model and analyze distributed systems including distributed sensors and actuators. We then consider identification of distributed systems via adaptive wavelet neural networks (AWNNs) by taking advantage of the ...
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 ...
Full Custom VLSI Implementation of Time-Recursive 2-D DCT/IDCT Chip
(1993)
Discrete Cosine Transform (DCT) based compression techniques play an important role in today's digital applications such as high definition television (HDTV) and teleconferencing which require high speed transmission of ...
VLSI Architectures and Implementation of Predictive Tree- Searched Vector Quantizers for Real-Time Video Compression
(1992)
We describe a pipelined systolic architecture for implementing predictive Tree-Searched Vector Quantization (PTSVQ) for real- time image and speech coding applications. This architecture uses identical processors for both ...
Optimal Wavelet Basis Selection for Signal Representation
(1994)
We study the problem of choosing the optimal wavelet basis with compact support for signal representation and provide a general algorithm for computing the optimal wavelet basis. We first briefly review the multiresolution ...
Time-Recursive Computation and Real-Time Parallel Architectures, Part I: Framework
(1993)
The time-recursive computation has been proved as a particularly useful tool in real-time data compression, in transform domain adaptive filtering and in spectrum analysis. Unlike the FFT based ones, the time-recursive ...
VLSI Implementation of a Tree Searched Vector Quantizer
(1990)
The VLSI design and implementation of a Tree Searched Vector Quantizer is presented. The number of processors needed is equal to the depth of the tree. All processors are identical and data flow between processors is ...
Systolic Architectures for Signal Compression and Discrimination
(1994)
In this dissertation we propose systolic architectures for several classes of signal processing computations including schemes based on vector quantization and high order crossings techniques. The systolic concept is adapted ...
