User microprogrammable processors for high data rate telemetry preprocessing

The use of microprogrammable processors for the preprocessing of high data rate satellite telemetry is investigated. The following topics are discussed along with supporting studies: (1) evaluation of commercial microprogrammable minicomputers for telemetry preprocessing tasks; (2) microinstruction sets for telemetry preprocessing; and (3) the use of multiple minicomputers to achieve high data processing. The simulation of small microprogrammed processors is discussed along with examples of microprogrammed processors

Graph model analysis of computer structures

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

Memory Utilization for a Dynamically Microprogrammed Computer

Microprogramming For Probability Distribution Sampling

Microprogramming of special instructions for sampling of random variates from any probability distribution is a means of increasing sampling speed. The diversity of sampling techniques is narrowed to one general algorithm: conditional bit sampling. Conditional bit sampling uses a high-speed uniform random number generator based on feedback shift registers to sample one bit at a time. The probability of a bit being a one in the j-th position of a binary expanded variate is stored in a table of conditional probabilities. A comparison with the pseudorandom number yields a one or zero. The table of conditional probabilities is generated once and passed through an instruction to the microprogram which performs the sampling. One user instruction is issued for each variate returned

Architecture and data processing alternatives for the TSE computer. Volume 2: Extraction of topological information from an image by the Tse computer

A simple programmable Tse processor organization and arithmetic operations necessary for extraction of the desired topological information are described. Hardware additions to this organization are discussed along with trade-offs peculiar to the tse computing concept. An improved organization is presented along with the complementary software for the various arithmetic operations. The performance of the two organizations is compared in terms of speed, power, and cost. Software routines developed to extract the desired information from an image are included
