A Distributed Logic Memory with Two-dimensional Access, as Applied to a Highly Parallel Processor

Description: Although more sophisticated designs of associative memories are not yet economically practical, with the dynamic advances in integrated circuitry currently taking place, the day appears not long off for an economical sophisticated associative memory to become a reality. This describes a general outline of a sophisticated DLM, but it also describes the actual logic involved in a building a working model. The design process involves formulating a set of commands sufficient to perform the desired … more

Design and Implementation of a TRAC Processor for Fairchild F24 Computer

Description: TRAC is a text-processing language for use with a reactive typewriter. The thesis describes the design and implementation of a TRAC processor for the Fairchild F24 computer. Chapter I introduces some text processing concepts, the TRAC operations, and the implementation procedures. Chapter II examines the history and -characteristics of the TRAC language. The next chapter specifies the TRAC syntax and primitive functions. Chapter IV covers the algorithms used by the processor. The last chapter d… more

Macro Control Structures for Structured Programming in ALC

Description: This thesis describes a set of computer program control structures which permits the application of certain structured programming techniques to the IBM/360 assembly language (ALC). The control structures are implemented by programmerdefined instructions known as macros. A history of computer software is presented, providing a basis for the emergence of structured programming. A survey of the major concepts of structured programming with special attention to control structures and their signifi… more

The Applications of Regression Analysis in Auditing and Computer Systems

Description: This thesis describes regression analysis and shows how it can be used in account auditing and in computer system performance analysis. The study first introduces regression analysis techniques and statistics. Then, the use of regression analysis in auditing to detect "out of line" accounts and to determine audit sample size is discussed. These applications led to the concept of using regression analysis to predict job completion times in a computer system. The feasibility of this application o… more

A Tool for Measuring the Size, Structure and Complexity of Software

Description: The problem addressed by this thesis is the need for a software measurement tool that enforces a uniform measurement algorithm on several programming languages. The introductory chapter discusses the concern for software measurement and provides background for the specific models and metrics that are studied. A multilingual software measurement tool is then introduced, that analyzes programs written in Ada, C, Pascal, or PL/I, and quantifies over thirty different program attributes. Metrics com… more

An On-Line Macro Processor for the Motorola 6800 Microprocessor

Description: The first chapter discusses the concept of macros: its definition, structure, usage, design goals, and the related prior work. This thesis principally concerns my work on OLMP (an On-Line Macro Processor for the Motorola 6800 Microprocessor), which is a macro processor which interacts with the user. It takes Motorola assembler source code and macro definitions as its input; after the appropriate editing and expansions, it outputs the expanded assembler source statements. The functional objectiv… more

Simulation of the IBM System/7

Description: This thesis describes the simulation of the IBM SYSTEM/7. The research leading to this thesis involved the development of a PL/I computer program that runs on an IBM 360/50 computer and simulates the IBM SYSTEM/7. Various methods of simulation are examined and guidelines for computer simulation of another computer are established. The SYSTEM/7 simulator (SIM/7) is the heart of this thesis. SIM/7 simulates the IBM SYSTEM/7 entirely with software as opposed to an emulator which involves the combi… more

The Design of Microcomputer-Based Sound Synthesis Hardware

Description: Microcomputer-based music synthesis hardware is being developed at North Texas State University (NTSU). The work described in this paper continues this effort to develop hardware designs for inexpensive, but good quality, sound synthesizers. In order to pursue their activities, researchers in computer assisted instruction in music theory, psychoacoustics, and music composition need quality sound sources. The ultimate goal of my research is to develop good quality sound synthesis hardware which … more

A Real-Time Merging-Buffering Technique for MIDI Messages

Description: A powerful and efficient algorithm has been designed to deal with the critical timing problem of the MIDI messages. This algorithm can convert note events stored in a natural way to MIDI messages dynamically. Only limited memory space (the buffer) is required to finish the conversion work, and the size of the buffer is independent of the size of the original sequence (notes). This algorithm's real-time variable properties suggest not only the flexible real-time controls in the use of musical as… more

A New Framework for Classification and Comparative Study of Congestion Control Schemes of ATM Networks

Description: In our work, we have proposed a new framework for the classification and comparative study of ATM congestion control schemes. The different aspects on which we have classified the algorithms are control theoretic approach, action and congestion notification. These three aspects present of the classification present a coherent framework on which congestion control algorithms are to be classified. Such a classification will also help in developing new algorithms.

Multiresolution Signal Cross-correlation

Description: Signal Correlation is a digital signal processing technique which has a wide variety of applications, ranging from geophysical exploration to acoustic signal enhancements, or beamforming. This dissertation will consider this technique in an underwater acoustics perspective, but the algorithms illustrated here can be readily applied to other areas. Although beamforming techniques have been studied for the past fifty years, modern beamforming systems still have difficulty in operating in noisy en… more
