System for acquisition and filtration of the data from a vertex detector on the base of drift chambers

Algorithms for the selection of useful infopmation and apparatus for acquisition, filtration, and collection of information from the vertex detector, based on drift chambers, are described. This detector is used in the experiments on the search for and study of new short-lived particles with the lifetime of the order of 10-12-10-13 s. The system consists of special crate controller, storage device, and hardware processor and allows to redect background interactions 14 times with a 50% level of charmed particle detection. The maximum time of the problem resolving is about 30 μs. The proposed dibugging technique permits to check the system under conditions close to real ones
