  • A schemata model of real-time information processing systems

    Creator:
    Szulewski, Paul A.
    Abstract:
    In an attempt to provide a practical means to measure the information processing capacity of a real-time digital processing system a theoretical framework, the Real-Time Schemata, whose basis is a schematic description and a measure of "useful information," is presented. The description applies to processes that would typically be implemented...

  • Improving the Karatsuba-Ofman multiplication algorithm for special applications

    Creator:
    Erdem, Serdar S.
    Abstract:
    In this thesis, we study the Karatsuba-Ofman Algorithm (KOA), which is a recursive multi-precision multiplication method, and improve it for certain special applications. This thesis is in two parts. In the first part, we derive an efficient algorithm from the KOA to multiply the operands having a precision of 2[superscript...

  • Hybrid-Meshnet, a local area mesh network with distributed control

    Creator:
    Kang, Cheoul Shin
    Abstract:
    Hybrid-Meshnet is a communication subnet architecture for local area networks (LANs) designed to achieve a high degree of network performance and flexibility. These objectives are achieved by utilizing a dual channel structure. A token ring is used for short or prioritized data transmissions. A complimentary mesh network with arbitrary data...

  • Implementation of display control node for a distributed microcontroller network

    Creator:
    Xu, Yan, 1954-
    Abstract:
    As hardware becomes cheaper and cheaper, there is an increasing interest in the implementation of distributed control networks with microcontrollers. Such networks are usually inexpensive and of high performance. In this thesis work, a low-cost display control unit for COLAN, a control-oriented network, is designed. The system is based on...

  • Motion detection algorithm using wavelet transform

    Creator:
    Lee, Jeongmin
    Abstract:
    This thesis presents an algorithm that estimates motion in image sequence using wavelet transform. The motion detection is performed under unfavorable conditions of background movement, change of brightness, and noise. The algorithm is tolerant to brightness changes, noise, and small movement in the background. The false alarm rate of motion...

  • Program allocation for hypercube based dataflow systems

    Creator:
    Freytag, Vincent R.
    Abstract:
    The dataflow model of computation differs from the traditional control-flow model of computation in that it does not utilize a program counter to sequence instructions in a program. Instead, the execution of instructions is based solely on the availability of their operands. Thus, an instruction is executed in a dataflow...

  • Fast Galois field arithmetic for elliptic curve cryptography and error control codes

    Creator:
    Sunar, Berk
    Abstract:
    Today's computer and network communication systems rely on authenticated and secure transmission of information, which requires computationally efficient and low bandwidth cryptographic algorithms. Among these cryptographic algorithms are the elliptic curve cryptosystems which use the arithmetic of finite fields. Furthermore, the fields of characteristic two are preferred since they provide...

  • Taskmaster II, a versatile distributed system for control

    Creator:
    Schaal, Hans-Werner
    Abstract:
    This thesis discusses a special type of a versatile, distributed control system, the Taskmaster II. It includes a detailed specification of a readily realizable Taskmaster system utilizing a layered communication among units, oriented on the ISO OSI seven layer model. The specification was developed from the analysis of previous research...

  • Overcoming the singularity problem in digital image restoration

    Creator:
    Osta, Ahmad M.
    Abstract:
    A recorded image is a degraded version of an original image. The process of removing the degradations is called restoration. Two types of degradations are considered in this thesis: namely, linear motion and defocused lens blurrings. Using the direct deconvolution technique to restore blurred images is impossible if the blurring...

  • A micro data flow (MDF) : a data flow approach to self-timed VLSI system design for DSP

    Creator:
    Merani, Lalit T.
    Abstract:
    Synchronization is one of the important issues in digital system design. While other approaches have been intriguing, up until now a globally clocked timing discipline has been the dominant design philosophy. However, we have reached the point, with advances in technology, where other options should be given serious consideration. VLSI...
