      Ways of implementation of a high-performance input/output subsystem for MP-3 multiprocessor are described. The MP-3 structure description is given, the way of MP-3 combining with a host-computer to create a multicomputer is analyzed and requirements to the input/output subsystem features to satisfy problems to be solved are formulated. Different options о the input/output subsystem features to satisfy problems to be solved are formulated. Different options of the input/output subsystem organization a.re considered. The analysis of several options and selection of the most optimal of them are performed basing on MP-3 specifications. The element base choice is substantiated to implement this selected option. Information concerning this subsystem analogs and their performances is given.

      The description of circuit engineering implementation of an input/output processor for MP-3 multiprocessor is given. The input/output subsystem combining with a multiprocessor is described. The design block diagram is considered and technical specification of principal nodes are presented. The choice of the element base is substantiated and brief description of elements in use is given. Test results are included.
