Kovalyov N. Efficiency enhancement of homogeneous digital integrating structures in automatic real-time systems

The thesis deals with the productivity improvement of the digital integrating structure (DIS), built on the FPGA bases. It is possible to reach this by an organization of Stieltjes numerical integration with implementation of the On-line arithmetic and development of necessary methods, techniques, approaches and DIS hardware. The examinee - the organizing process of the Stieltjes numerical integrating. The methods of the digital integrating structure theory, on-line arithmetic, organization of computing processes, modeling, hardware design on FPGA bases with modern CAD/CAM are used. The methods of on-line calculating of Stieltjes integral increment in symmetric redundant numerical notation; extrapolation; transition from complex functions to Shannon differential equation system are developed. An approach to the functional control of the quasi-parallel DIS is proposed. Hardware (on FPGA bases) and software DIS models are designed. Similar advanced DIS are considered as the basis of perspective onboard computing systems.
