A method of developing a checkable self-recovery floating-point pipeline system

Abstract

The objective nature observed in the development of the computer world makes it possible to predict requests for the development of promising computer systems. The parallelism and fuzziness of the natural world encourages the development of pipeline systems for the processing of approximate data. The progressive development of high-risk objects increases the requirements for safety-related systems in improving the checkable and fault-tolerant solutions used in them. A method for developing a checkable fault-tolerant floating- point pipeline system is proposed. Matrix circuits of pipeline sections are unified in the form of lines of identical elements. The operands and floating-point results obtain an additional bit excluded from the calculations. Its movement creates many versions of calculation execution, ensuring the checkability of circuits and their fault tolerance in the form of self-recovery when selecting a version that excludes a faulty element. The method uses the synergy of different types of performed functions to simplify the system and to counter faults.
