The handbook sets out the basics of new knowledge in information tech-nology. The technology is based on the use of automatic memory circuits and is oriented to the processing of hierarchical information. In the handbook are con-sidered: the principle of hierarchical program control, the theory of multifunc-tional automata of Marakhovsky (1st, 2nd and 3rd kind) and multi-level automa-ta. Methods of synthesis of multifunctional and multilevel new elementary memory circuits. Automatic continuous time, within which it became possible to consider the functioning of multifunctional automata, new memory circuits and the construction on their basis of typical reconfigurable devices, such as: regis-ters, counters, control devices, microprocessors, computers and other devices and computer systems are considered. The methods of hierarchical software and the foundations for constructing neurons and neural networks based on automatic memory circuits are described. The guide material will allow developers of computer devices to create competitive reconfigurable processors, computers and computer networks. The handbook can be useful to students of technical universities, postgraduate students.
