    Graph theory is applicable to the solving of problems in nearly every field of scientific study. The purpose of this thesis is to consider its applications in representing and analyzing digital computers. Fundamental graph theory definitions, the types and the properties of the directed graphs, the matrix representation, and several reduction techniques are discussed. The blocking gate method for diagnosing computer systems is described and applied to the Scientific Control Corporation (SCC) 650 for its fault-diagnosis. Microprogramming has been a significant trend in hardware and software designs of computers. Microprogrammed computers are discussed in comparison to conventional computers. A general scheme utilizing four nodes generates directed graphs for both types of architecture. The directed graphs are studied with respect to the flexibility and cost parameters --Abstract, page ii

    Towards a design of HMO, an integrated hardware microcode optimizer

    This paper discusses an algorithm for optimizing the density and parallelism of microcoded routines in micro-programmable machines. Besides presenting the algorithm itself, this research also analyzes the algorithm\u27s uses, design integration problems, architectural requirements, and adaptability to conventional machine characteristics. Even though the paper proposes a hardware implementation of the algorithm, the algorithm is viewed as an integral part of the entire microcode generation and usage process, from initial high-level input into a software microcode compiler down to machine-level execution of the resultant microcode on the host machine. It is believed that, by removing much of the traditionally time-consuming and machine-dependent microcode optimization from the software portion of this process, the algorithm can improve the overall process --Abstract, page ii

    This paper deals with the outline, design features and performance of the KT-Pilot, which is a binary, parallel, high-speed digital computer developed for research into the technical problems encountered in high-speed computers. This machine, although a small-sized experimental one, has many unique features : a microprogram control system utilizing a newly developed phototransistor fixed or read-only memory, asynchronous operations adopted to speed up the machine, a continuous-sheet Supermalloy thin film memory first put into practical use as the computer memory in this country, high-speed logic circuits employing fast mesa transistors and both mesa and gold-bonded diodes as circuit components, and so on. Two types of core memories, i.e. current-coincident type and word-organized type, constitute the main memory together with the above-mentioned thin film memory. A photo-tape reader and a Flexowriter are used respectively as the input and output devices. This machine has been operating stably at our laboratory, and its performance is very satisfactory
