STRUCTURES OF SIGNAL CORRECTION CIRCUITS BASED ON DOUBLE MODULAR REDUNDANCY WITH COMPUTATION CONTROL

Annotation

Methods of synthesis of fault-tolerant discrete devices and systems are investigated. A block dia-gram of signal correction based on the use of double modular redundancy with control of calculations by a preselected feature is proposed. Three options for the implementation of this structure are analyzed. The first structure is based on the control of computations by a copy of the original device by code with repetition, which in fact implies the use of a computation control scheme by the duplication method. The second structure is the control of computations based on a parity code. In the third structure, the control scheme uses a special code with summation of the coefficients of weighted transitions from category to category in the information vector, which makes it possible to construct a control scheme that is simpler than with duplication. Results of experiments on evaluating the efficiency and complexity of the tech-nical implementation of each of the proposed structures with the use of control combinational circuits LGSynth’89 and MCNC Benchmarks are presented. The proposed structures of signal correction circuits based on double modular redundancy are built from standard blocks, which allows them to be widely used for synthesis of fault-tolerant discrete devices.
