METHOD TO FORM FAULT-TOLERANT COMPUTING SYSTEM AND FAULT-TOLERANT COMPUTING SYSTEM Russian patent published in 2012 - IPC G06F15/16 

FIELD: information technologies.

SUBSTANCE: system comprises four faces. Each face comprises a parallel operating double-processor microprocessor system, where one central microprocessor (CP), performs the main computing load, and the second one - an input-output processor (IOP), performs data preparation for CP, reacts at external interrupts, interacts with periphery and implements functions of a monitoring and diagnostics system, a double-port random-access device, interfacial exchange equipment, a reconfigurator comprising configuration registers, registers of mode control operation and registers of test and functional face operability criteria, logical equipment of reliable disconnection of secondary power supply sources in case of face failure, with the help of distributed majorising of monitoring signals from all active faces, a circuit of initial start-up and a face adapter. The system comprises a cycle generation device for synchronisation in each cycle of a cyclogram for start of operation of all system faces that operate asynchronously during the cycle.

EFFECT: system reliability improvement.
