Structural Analysis of Multi-Core Processor and Reliability Evaluation Model

In the present paper, the models of structural analysis and evaluation of efficiency indicators (reliability, fault tolerance, viability, and flexibility) of a multi-core processor with variable structure, equipped with multi-functional cores, are considered. Using logical–probabilistic methods, the following has been developed: models for evaluating the reliability and fault tolerance of processor cores as multi-functional elements; logical–probabilistic models of the shortest paths, flexibility, and performance conditions for successful operation of multi-core processors based on multi-functional cores; and models for estimating the reliability, fault tolerance, and lifetime of multi-core processors considering all possible states of performance. The results of the structural analysis of two-core and four-core processors and the trends of increasing the efficiency indicators of multi-core processors are presented.
