[en] The state and trends in development of parallel methods for detection of event multiplicity and coordinates employed in high-energy physics are examined. It is noted that both analog and digital logic devices and processor elements have been traditionally used to increase the speed and flexibility of devices created for physics-event sampling electronic system designed for nuclear physics. A number of examples are provided that illustrate the wide possibilities of analog-to-digital converters with parallel input-voltage conversion and a maximum clock frequency of ≥100 MHz. Methods for construction of parallel counters are described, and the outlook is examined for their use in the creation of efficient devices for event sampling by signal multiplicity, special-purpose processors, and parallel data compressors. Also examined are methods for the design of parallel coders and majorant coincidence systems employing syndrome coding and a method of ones compression based on regular matrix structures. 49 refs., 21 figs., 2 tabs
