Description: The formalization of the process of information processing on the basis of signature analysis was completed and the method of synthesis of multichannel devices of test control was improved in the conducted research. In this case, the algorithm of data processing in the multichannel signature analyzer is proposed, and its architecture, which is aimed at verifying the objects of distributed systems. Architecture of the signature analyzer allows you to control the data by groups is considered in the work. At the same time reception of the information sequence can be carried out in one cycle of the clock generator, if it allows the bit of the analyzer. In that case, if the bit size of the analyzer is less than the length of the group of discharges, then its processing can be carried out over several cycles of the clock generator. Multichannel signature analyzer allows you to quickly change the number of active inputs in accordance with the number of discharges that require processing in one cycle pulse generator. The practical implementation of the proposed approach allows you to create devices that are able to use different polynomials when testing the test sequences. It is possible to achieve a significant reduction of hardware costs and simplify the technical implementation of signature analyzers, due to the automatic generation of service information in devices.
